Plus Size Strap-Ons & Harnesses

Underwear that happens to hold a dildo in place, that is the whole idea behind this boxer brief style harness. It looks and feels like a regular pair of shorts, so putting it on never feels like gearing up for a production.

Pull them on and the first thing you notice is the familiar, soft waistband, nothing stiff or uncomfortable about it. The stretchy O-ring sits ready to take most dildo bases, so fitting your chosen toy is quick and fuss-free. Because the fit is snug and supportive, the elastic waistband carries the weight instead of leaving it all on the O-ring, which means you can move, shift position and stay strapped in without constant adjusting. They are discreet enough to wear under your clothes, and if you want to go a different route entirely, they double nicely as a home for a packer.

Made from a flexible cotton and spandex blend by XR Brands, this active style harness is machine washable, comes in black, and holds up well for wear that lasts beyond a quick try-on.

Forget the buckle-and-strap wrestling match. The Rebel Harness by Strap-On-Me looks and feels like lingerie, but it is built to hold your dildo of choice steady through whatever you have planned.

Slip it on and the first thing you notice is how much it feels like a favorite pair of panties rather than gear. The stretchy waistband moves with your body instead of digging in, and the garter belts adjust so the fit stays comfortable no matter how things shift. Once you attach your dildo through the sturdy O-ring, it stays put through the thrusting, the changing positions, the whole encounter. The open-back design keeps things easy too, giving you clear access for spanking or a quick switch in position without breaking stride.

This strap-on harness is meant for pegging, for switching, for anyone who wants the mechanics to disappear so the moment does not. In a smooth nylon, elastane and microfiber blend with a flexible, soft-fitted feel, it comes with an O-ring built in for attaching your dildo, which is sold separately.

Some strap-on harnesses fight you before you even get started. This one from XR Brands is built for comfort first, with a wide rear support belt that keeps everything steady while you move however you like.

The soft lining settles against your skin instead of digging in, while the flexible straps adjust to fit rather than forcing you to fit them. The nickel-free ring snaps in securely and is sized to work with most standard dildos that have a base or balls to hold them in place, and the snap design means you can swap in a ring of your own if you want other size options later. There is even a small looped elastic strap built in, so a remote can ride along for hands-free play.

This universal harness comes with sturdy metal hardware throughout, so nothing feels flimsy once you get going, and the smooth, flexible feel comes from PU-coated material paired with polypropylene and elastic strapping plus nickel-free alloy and iron hardware. It fits most body types comfortably. Pick your favorite dildo to pair with it, since one is not included, and you will have a strap-on harness setup that stays comfortable no matter how long you play.

Bright straps, easy fit, and a harness built to make strap-on play simple for anyone new to it or coming back for more. This rainbow strap-on harness from XR Brands pairs with two silicone O-rings so you can hold a range of flanged dildos securely in place, with a wide adjustable waist and a padded front panel that keeps things comfortable throughout.

Start by picking the O-ring that matches your dildo's base, it should sit snug and stay put rather than slipping through. Once it's secured, step into the harness and pull the plastic buckles to bring the waist and crotch strap in to a fit that feels close but not tight. The wide back strap crosses above the hips and helps carry the weight of a bigger toy, so nothing sags or shifts mid-play, while the triangular pad up front cushions your skin against the base of the dildo and cuts down on chafing. From there, add lube if you like and let your partner enjoy the ride, hands stay free the whole time since this strap-on harness holds everything in place on its own.

Made from a mix of nylon, faux leather, ABS and metal hardware plus flexible silicone rings, this harness spot cleans easily with mild soap, warm water and a damp cloth, and it works with your own dildo of choice since none is included.

One harness, two rings, and a whole lot of possibilities. The Unity Double Penetration Strap On Harness by XR Brands lets you build the exact setup you want, whether that means a single dildo or a full double penetration scene.

Start by choosing your rings. The metal O-rings give a firmer, more rigid hold, while the silicone pair offers a bit of stretch and give for a softer fit. Snap either set, or both, onto the dual ring base, then thread on the dildos of your choice, sold separately so you can pair the harness with whatever fits the mood. The nylon straps buckle on and adjust easily around the waist, with a smooth surface that sits comfortably against skin and flexible construction that moves with you instead of against you. Once it is cinched down, the design keeps everything held firmly in place, so the focus stays on the two of you rather than adjusting gear mid-scene.

This dual ring strap on harness works just as well as a solo strap-on for vaginal or anal play as it does for double penetration, making it a flexible piece to build a whole collection of scenes around. In nylon, metal and silicone, it comes complete with the harness, two silicone O-rings and two metal O-rings, ready to pair with your favorite dildos.

A jock-style harness that fits like your favorite waistband, not a piece of gear you have to fight with. The Avalon strap on harness is built for comfort, so it stays put through long sessions instead of pinching or riding up.

Step into it and the first thing you notice is the elastic waistband, wide and supportive, sitting easily against the skin. The X style fabric panels hold the dildo securely against the body, cutting down on chafing so extended wear stays comfortable rather than something to endure. Slide-through buckle straps let you adjust the fit, and because the front uses a universal O-ring, you can switch in a different wide-base dildo without needing a new harness. The open rear straps keep things airy and leave room for other kinds of play, whatever direction that takes you.

Made from smooth-surfaced spandex, nylon and elastic with metal hardware, this jock strap harness from XR Brands adjusts to fit a wide range of waists and works with wide-base dildos sold separately.

Fit is usually where harnesses fall apart, literally. This one is built to actually stay put, with a rig that adjusts to a wide range of waist sizes and an open rear and crotchless front design that keeps access easy for anyone wearing it.

Once you strap in, the nylon waist and thigh straps take the guesswork out of sizing, and you can trim them down for a custom fit with no extra strap flapping around. The neoprene front plate sits at an angle that keeps the attached plug feeling natural rather than stiff or awkward, while the open crotch and rear design leaves room to move, touch or access what you need mid-scene. The included O-rings mean you're ready to swap in O-ring compatible accessories whenever the mood calls for it, and since this Doc Johnson strap on harness works with the full range of Vac-U-Lock toys, switching things up is simple.

Splashproof and made from a sturdy mix of nylon, neoprene and ABS plastic, this harness for strapping on is built to handle real use without missing a beat.

A harness that actually fits is the whole point, and this one is built to fit generously and stay put. The Sportsheets Divine Diva Plus Size Strap-On Harness gives you a hands-free way to wear a dildo of your choosing, with a shape and strap system made for real bodies rather than one narrow size range.

Put it on and the first thing you notice is the padded panel against your skin, soft and smooth rather than stiff or scratchy. The straps adjust on multiple sides, so you can bring the fit in snug around the waist and thighs without pinching or riding up, whether you are built curvier or just want extra room to move. Instead of hunting for a dildo that matches one fixed opening, you get a choice of support rings, so you can pick the one that suits your toy instead of measuring everything first. Once it is secured, the fit stays close to the body through movement, so thrusting feels connected and controlled rather than wobbly, and both beginners and more experienced players can settle into a rhythm without fussing with the gear.

This strap-on is meant to work for anyone, solo or with a partner, and the soft nylon straps are shaped to move with you instead of cutting in. In a mix of faux leather, nylon and polyester with plastic and metal hardware, this harness comes in black, is phthalate-free, and cleans up with a simple spot clean.

A strap-on harness works best when it disappears into the background and lets you focus on the rest of the scene, and this wide band design is built for exactly that. It holds your chosen dildo securely in place so both partners can move freely, hands staying right where you want them.

Putting it on is simple: the wide waistband adjusts to fit comfortably around most body types, while the back supporting strap follows the contours of your body instead of digging in or riding up. Once it's positioned, you snap your dildo of choice into the O-ring and you're ready to go. Because the ring uses a snap-in system from XR Brands, you're not locked into one size forever - swap it out for a different ring whenever you want a change, and most cock rings will slot right in.

Made from black faux leather with elastic straps and metal ring hardware, this adjustable harness for strap-on play fits a wide range of waist sizes and comes with one interchangeable ring included, with the dildo itself sold separately. Clean it by spot cleaning only, and it'll stay ready for your next scene.

Some harnesses fight you before the fun even starts. This one skips the fuss entirely, built right into a pair of boxer-briefs so wearing a strap-on harness feels as simple as getting dressed.

Pull them on like your regular underwear and that's the first thing you notice: a cotton and spandex blend that moves with you instead of against you. No separate straps to buckle, no adjusting a tangle of harness gear. When you're ready, just pop your dildo into the stretchable O-ring at the front and you're set. The elastic band is built to stay supportive under the weight of larger dongs, so it holds its position while you focus on your partner instead of your gear. Keep your clothes on over top for a discreet look, or drop your pants to reveal the strap-on underneath, whichever suits the moment.

Made by XR Brands in a cotton, spandex and rubber blend, this active style harness goes in the machine on a cool wash when you're done, ready to wear again next time. Dildo not included.

A strap-on harness that gets out of its own way, so the toy you pair it with can do the work. This Thank Me Now design goes on and off with ease and adjusts to fit a wide range of body shapes, making it a genuinely unisex pick for solo play or partners taking turns.

Slip it on and the velcro sides and stretchy webbing let you dial in the fit before you move, rather than fighting a fixed strap. The plus size range means there is room to loosen or tighten until the waist sits right, and once it is set, you are free to focus on the toy itself rather than the harness. The o-ring is built to hold a range of shapes, so this strap-on harness works with Get Lucky Real Skin dildos, Jelly Love dildos, or the Confetti and Glitter Dick dildos, and it pairs just as easily with a single or double-ended toy for partner play, making this harness style a flexible fit for the moment.

Made from black polyester and elastic, with adjustable velcro sides and stretchy webbing, it is built to flex with you rather than the other way around.

A harness that actually accounts for real bodies is harder to find than it should be, and this one closes that gap. Made by Sportsheets, it's built with a wide adjustable range that fits comfortably across a broad span of sizes and hip measurements, so the fit feels secure rather than improvised.

Once it's on, the open rear design and sheer thigh straps keep things breathable and let you move naturally instead of feeling boxed in by bulky webbing. The soft front panel holds any flared-base dildo or dong in place, and the included set of O-rings means you can swap sizes until one sits snug and steady. There's also a channel built into the front plate for a bullet vibrator, so if you want added vibration running through whatever shaft you're wearing, that option is right there waiting. As you move, the design is meant to support a natural range of motion rather than fight against it, which matters whether you're leading the action or just getting used to wearing a strap on harness for the first time.

Made from a mix of polypropylene webbing, soft neoprene and rubber O-rings, this adjustable strap on is machine washable and comes without a dildo, giving you free choice of your own flared-base attachment.

The Red Rider harness set puts a curved companion right where you want it, letting whoever wears it take the lead with a dildo shaped for finding the spot. This CalExotics design pairs a padded universal harness with a firm red dong built to reach deep and curve toward the g-spot.

Buckle in and the padding is the first thing you notice, softening the straps against skin so the fit feels secure rather than stiff. The waist and thigh straps adjust generously, so the harness settles onto most body types without a fuss. Once it's on, the smooth, curved dildo does the work, its shape angled to press against the g-spot and vaginal wall as you thrust and grind, building toward a satisfying finish. The surface stays smooth and flexible throughout, so movement feels natural rather than rigid. For couples who want more, there's a pocket built into the harness that holds a separate vibrating device, letting you layer in vibration against the g-spot while you move together.

The dong is phthalate-free PVC with a chrome-plated iron ring and nickel-plated iron snaps on the polypropylene harness, giving this strap-on set a sturdy build with a comfortable, adjustable fit.

Strap-on play doesn't have to be complicated, and this beginner-friendly kit proves it. The Sex & Mischief Strap-On and Silicone Dildo Kit pairs an adjustable four-way harness with the Sportsheets 'Please' silicone dildo, so you have everything you need to get started right out of the box.

Start by stepping into the harness, which is made from soft polyester fabric and sturdy polypropylene webbing, with plastic hardware and a nitrile O-ring to hold the dildo securely in place. The straps adjust easily to fit comfortably around the hips, and the design stays comfortable whether this is your first time trying strap-on play or you're simply adding a new set to your collection.

The included dildo has a slender, beginner-friendly shape with a smooth surface, made specifically for vaginal stimulation, so it eases in comfortably and moves naturally with your body once the harness is fitted and adjusted.

When you're done, cleanup is simple since the entire kit is machine washable, so you can wash up and store it away without any fuss between uses.

Some kits ask you to piece things together. This one just works, straight out of the box, giving you a harness and dildo built to move together instead of fighting each other.

Start with the harness itself: it adjusts to fit comfortably around a wide range of hip sizes, so getting strapped in feels secure rather than fussy, with nothing digging in or slipping loose mid-session. The interchangeable ring system means the dildo included here is just the beginning, since the harness is built to hold other dildos too, once you're ready to switch things up. For now, the realistic dong that comes with it is plenty to explore, with a lifelike shape, a textured surface and a base finished with balls for a genuinely intimate feel. Its shape is generously sized without being unwieldy, made for satisfying penetration whether you are using it vaginally or anally. When you want hands-free play, flip it around to the suction cup base and stick it to any smooth surface, solo or with a partner, and let the harness take a back seat entirely.

Made from body-safe TPE with a leather and neoprene harness and metal hardware, this Nasstoys strap-on harness with dildo is waterproof and works best with a water-based lubricant for a smooth, comfortable glide. Think of it as your go-to strap-on set, ready whenever the mood strikes.

Pegging made simple: swap the dildo, keep the harness. This pegging kit pairs a Dillio platinum silicone dildo with the Body Dock SE harness system from Pipedream, so attaching and switching toys is a matter of pressing suction cup to docking plate rather than fumbling with rings or snaps.

Buckle in and the form-fitted body plate settles against you, held snug by heavy duty nylon straps with quick-release buckles that adjust to fit a wide range of waist sizes. Line up the suction cup on the smooth, flexible dildo with the docking plate and it locks into place with a simple push, no twisting or wrestling required. The angled dock helps keep the dildo standing at the right angle for the whole encounter, and because the docking plate accepts other suction cup dildos too, this docking kit works with toys you may already have on hand, as long as the cup fits the size the plate is built for.

The dildo itself glides smoothly on entry, with a shape sized to feel substantial without being unwieldy, comfortable for anal or vaginal play. Clean it up, let the harness dry fully, and it is ready to go again whenever the mood strikes.

Two dildos, one harness, and none of the usual fumbling with rings or snaps. The Dillio Platinum Body Dock SE Fantasy Kit from Pipedream pairs a suction-cup harness with a pair of Dillio dildos, so switching between them, or between this kit and dildos you already own, takes seconds.

Setup starts with the harness itself: a flexible, form-fitted plate held on with heavy duty straps and quick-release buckles, built to sit comfortably against the body while staying put during play. Attaching a dildo is just a matter of pressing its suction cup onto the docking plate, no twisting or locking pieces required. From there you pick your dildo: the shorter one with its large, bulbous head, or the longer, subtly ridged one, each with a smooth, non-sticky surface that feels natural to the touch. Because both have suction cup bases, you can also stick them together and use them as a double dildo, giving you and a partner another way to play with the same kit. The angled suction dock helps keep whichever dildo you choose standing at the ready, so hands-free stimulation stays steady through vaginal or anal play.

Both dildos are made from platinum-cured silicone, prized for its smooth, non-reactive feel and durability, while the harness combines silicone, plastic, polyurethane and nylon for a secure, adjustable fit. This strap-on kit is built to work with most suction-cup dildos on the market, so it can grow with whatever you add to your collection later.

Lace, satin ribbon and a corset silhouette make this strap on harness look like lingerie first and hardware second. It is built to hold your favorite O-ring compatible toy while looking like part of the outfit rather than something bolted onto it.

Step into it and the first thing you notice is the fit: the corset-style rear laces up snug, and the straps adjust generously to suit a wide range of hip sizes, with room to trim them down for a fit that is genuinely yours. The front plate feels smooth and flexible against the skin, and its pocket is sized to hold a bullet vibrator, or you can thread a dildo through with the help of the included O-ring set, which comes in a range of sizes to match different flared bases. The open rear design leaves things on display and open for extra access, so play can shift easily from show to touch. Buckles stay low profile so nothing digs in, and the nylon strapping keeps everything held snug without feeling stiff.

This Sportsheets harness works well as an entry point into strap on play, or as a sexier upgrade to a harness collection that could use some style. In a mix of lace, satin and nylon with nickel-free metal hardware and ABS buckles, this adjustable harness is machine washable and ready to pair with the O-ring compatible toy of your choice, sold separately.

Two motors, one harness, and a lot more room for shared pleasure. The Gender X Sweet Embrace strap on vibe, from Evolved Novelties, pairs a curved, crowned vibe with a suede and faux leather harness, so wearing partner and receiving partner both get something to feel good about.

Start with the harness itself, adjustable at the waist and thighs with a velcro fastener so it settles into place around your body rather than someone else's fixed idea of fit. Slide the vibe into place and you have a wearable shaft with a textured, wavy, gently curved profile built for vaginal stimulation. Switch on the two motors, one in the head and one in the base, and each runs through its own set of vibrating speeds and functions, so the sensation can build in the tip, the base, or both together. Hand the remote to a partner, or keep it yourself, and the play turns hands-free whenever you want it to. Because the toy is fully submersible, you can carry the fun into the shower or bath without a second thought.

Made from phthalate-free silicone and ABS with a suede and faux leather harness, this strap-on vibe with harness is USB rechargeable, waterproof, and controlled by a remote that runs on its own batteries.

Some bodies get left out of strap-on design entirely. This one is built for a fuller figure from the start, with a harness that adjusts to fit real curves instead of asking you to make do.

The genuine leather harness sits around the waist and adjusts easily, so getting the fit right takes just a moment rather than a fight with straps. A metal o-ring holds the dong securely at the center, keeping it steady through changes in angle and pace. The dong itself has a smooth surface and enough flex to move naturally with you, with a suction cup base at the center for hands-free play if you want it.

Pipedream designed this plus-size strap-on to feel like it was actually made with a fuller figure in mind, not adapted after the fact. The waistband adjusts to fit larger waists comfortably, and the set comes in black or purple so you can pick what suits you. It is a plus size harness set that proves good fit should never be an afterthought.

Swapping toys mid-session should never feel like a project. The Body Dock SE harness by Pipedream lets you push any suction-cup dildo or vibrator onto its silicone docking plate and go, so the strap on becomes a base you can restyle whenever the mood changes.

Start with the fit: the flexible body plate curves against you instead of sitting stiff, and the nylon straps cinch through quick-release buckles so getting in or out never turns into a fumble. Once it's snug, press your chosen toy onto the angled dock. There are no rings to wrestle with and no snaps to line up, just a firm push until it locks in place. That angle also helps hold the dildo upright and steady, so it stays put through whatever rhythm you set.

When you're ready for a change, release the toy and dock a different one in seconds, which is the real point of a push and play harness like this. In silicone, nylon, ABS and PU coating, it comes in one generously sized fit built to adjust across a wide waist range (dildo not included).

Looks tough, feels easy to wear, and that is exactly the point. The Montero strap-on gives you a harness that reads as bold faux leather with silver hardware, built plus size for a comfortable fit.

Step into it and the straps do the adjusting for you, letting you dial in a fit around your hips from multiple angles without fuss. The ergonomic scrotum clearance means the design was thought through, not just strapped on, and if there is extra strap length hanging off the end, you can trim it down so nothing flops or catches. The interchangeable O-ring is where the action starts, and because the snaps take a range of ring sizes, you are not locked into one dildo forever. Pair it with a Merge Collection dildo and the matching harness silicone cushion to add stability during thrusting and penetration. Sportsheets built this strap on harness with that kind of everyday versatility in mind.

This strap-on harness comes in faux leather with metal hardware, is backed by a limited lifetime warranty, and is ready for the dildo of your choice, sold separately.

Meet the Gender Fluid Skylar Strap-On Harness, built to fit all bodies and gender identities without asking anyone to squeeze into a generic mold.

Start by adjusting the straps to your own hips rather than the other way around. The multi way adjustable fit lets you shape it exactly to your body, and the soft padding keeps things comfortable whether you are wearing it for a few minutes or a whole evening. Thank Me Now made this strap-on harness from nylon and polyurethane with metal and plastic hardware, so it stays flexible while you move.

When you are done, cleanup is simple: a gentle hand wash in cold water keeps the harness in good shape for next time. It fits a wide range of hip sizes, so it can work for you now and for partners later.

The dildo is not included, which means you get to choose whichever one fits your mood and pairs best with this harness.

Sizing up your strap-on collection should not mean starting from scratch, and that is exactly what this Pipedream harness solves. The Basix Universal Plus Size Harness is designed to fit comfortably and adjust easily, so getting set up for play takes barely any thought.

It comes with a trio of silicone O-rings in small, medium and large, letting you fit the harness to most Basix strap-on ready dildos as your preferences or your collection change. The straps are made from flexible nylon and PVC with a smooth surface, so putting it on and adjusting it for a secure fit is simple, even if this is your first universal harness.

The dildo is sold separately, so pick the size that suits you and get strapped in with confidence.
