Things to Consider When Shopping for Strap-on Underwear
The easiest way to research and find strap-on underwear that fits you is to take the same approach as when buying regular panties. The size of the undies and the quality of the materials come first; however, you’ll need to consider a couple of other things relating to the probes you want to use:
- Strap-on Harness Size: Typically, you want to choose products with elastic waistbands and a comfortable fit around your thighs. Opt for products with a measurements table on the packaging to ensure you have the perfect fit for your body. Another option is sticking to the standard sizes identical to the sizes of regular underwear and using them to determine which strap-on undies will fit you best.
- Materials: This is somewhat tricky since the quality of the material will determine how long you can wear the strap-on harness without feeling discomfort or chafing. It’s best to go for breathable materials, or microfiber mixes from nylon and elastane, which offer a soft texture but, at the same time, are durable and won’t stretch out easily or lose their color.
- O-ring Flexibility: some strap-on underwear harnesses come with externally attached O-rings which usually offer less flexibility when using different probes. We recommend choosing undies with integrated and reinforced O-rings that securely down your dildo during penetration while accommodating probes with different diameters.

Strap-On Underwear vs. Strap-On Harnesses
Strap-on underwear and standard strap-on harnesses come in different variations, offering many choices for those who want to indulge in this type of sex play. Despite their common purpose, they have several features that set them apart and might influence your choice of buying one or the other depending on the strap-on experience you already have.
Strap-on underwear is much more comfortable and easy to wear for extended periods. It is usually made from breathable materials that don’t chafe or break the skin even during vigorous movement, making it an excellent choice for longer thrusting sessions. Additionally, the general lack of straps makes this harness easier to put on, allowing the wearer to jump right into action when the mood strikes them. These properties make the strap-on underwear a perfect choice for beginners who want to get a handle on pegging or penetrating their partner with a probe. The strap-on underwear harnesses are also a practical choice for the receiver, as they usually feature flexible O-rings that can easily fit smaller and bigger probes.
On the other hand, strap-on harnesses are renowned for their erotic visual appeal and secure fit during penetration. They are made from materials such as nylon or leather, the latter being treated as a separate fetish in the BDSM community. The strap-on harnesses can feature multiple straps going around the waist, thighs, or hips, allowing you to fully engage in rough sex without any worry that the probe will fall off or your harness dildo will slip. Additionally, strap-on harnesses usually feature adjustable O-rings that can fit anything from tiny probes to monster dildos and often are sold with one or more probes included in the packaging.
Overall, buying a strap-on underwear or harness comes down to personal preferences. If you honestly consider the experience you desire and how often you intend to use the strap-on, choosing one or the other will become much easier!
