    Why We Picked It

    We chose the Vac-U-Lock Vibrating Dual Density Ultraskyn Set with Remote as our top choice for a Vac-U-Lock strap-on. The set comes with all you need to get started with strap-on play, beginning with a harness, dildo attachments, all the accessories, lube, and care products. We like the harness, as it is sturdy and very adjustable, fitting waists up to 69 inches.

    We also love the three dual-density dildos that are included in the set. These are made from Ultraskyn and have a very realistic feel. We also love that the set comes with a vibrating plug, allowing you to turn each of the dildo probes into a vibrating dildo; it is wirelessly controlled, and the plug is USB rechargeable.

    Vac-U-Lock Ultraskyn Cock with Ultra Harness

    Best Value

    Our Rating: 4.8/5
    Quality: 5/5
    Design: 4/5
    Ease of Use: 4/5
    Intensity: 5/5
    Recommended For: Everyone

    Why We Picked It

    We added the Vac-U-Lock Ultraskyn Cock with Ultra Harness as the best-value model because this kit offers excellent value. We love the jockstrap-style harness that is stretchable and can fit waists of up to 53 inches. Still, we found it not as sturdy if you have a very narrow waist. But the key thing about the harness is that it features a crotchless design, allowing you full access to the vagina, even being suitable for penetration.

    We like that you can choose between two sets, one with a 7-inch and another with an 8-inch dildo length. The dildos have a realistic design, with a tapered tip and a set of balls at the bottom. The dildos are relatively firm and provide a sense of fullness. We recommend it also because the Vac-U-Lock Ultraskyn Cock with Ultra Harness is waterproof, and you can use it with ease.

    Who It's For

    The Vac-U-Lock Ultraskyn Cock with Ultra Harness is a fantastic choice for many, as the set has a good harness and two dildo sizes to choose from.

    What Customers Are Saying

    The dildo probes are compatible with the Vac-U-Lock probe, but you can also use these with the provided Vac-U-Lock suction cup base that you can stick to most flat surfaces for hands-free play. The harness has an open-style design, is secure and easily adjustable, and can fit waists of up to 69 inches. We believe you will find this set very apt, mainly because it also comes with a bottle of lube and sex toy cleaner.

    Essential Things to Know about Vac-U-Lock Strap-Ons

    Here, we are specifically discussing Vac-U-Lock-compatible strap-ons; we want to refer you to our guide on how to choose Vac-U-Lock dildos and strap-ons, where we cover all the essential things about this type of sex toy. So, here we’ll only cover the basics you need to know when you select Vac-U-Lock strap-ons:

    • Harness adjustability – when you choose a Vac-U-Lock strap-on, you need to check and get a strap-on harness that is adjustable and very close to your actual size. To prevent the harness from feeling loose, only search for adjustable harnesses, which is a feature we always list in our product descriptions.
    • Vac-U-Lock plug – the Vac-U-Lock strap-on you get should include a suitable compatible plug. We recommend you get a Vac-U-Lock strap-on that features a detachable suction cup that will allow you to put on or remove and stick it to a clean, flat surface, turning any dildo attachment into a mountable hands-free sex toy.
    • Attachments – because you get very many options for Vac-U-Lock attachments, you need to consider the ones that are included in your chosen kit. We recommend you start with a model that features a moderately-sized dildo attachment and a Vac-U-Lock suction cup, while more experienced users can get a larger model.

    Final Words

    We hope that our list of the best Vac-U-Lock strap-ons is enticing and inspiring for you. Still, if you want to check out more options, we invite you to our sex toy store; we have a fully stocked offer of various strap-ons, dildos, vibrators, male toys, anal toys, sexy lingerie, BDSM tools, sexy lingerie, and so much more.
