The SpareParts Hardware Deuce strap-on harness has been designed for people with a bio penis, or to use with a packer. Though, we feel it can be worn by anyone. The joque strap style is super comfortable while being robust and sturdy enough for the most enthusiastic of strap-on play!

As with all SpareParts Hardware harnesses, the Deuce is made out of soft, breathable nylon and spandex fabric. Which means this can be cleaned easily, just throw it in the wash, following the instructions of course, or hand wash it. Very hygienic! Unique wicking elements that pull moisture away from the body.

The Duece has velcro on the belt strap, and further adjustable areas on the hip, and leg straps. These features provide extra stability and will suit a variety of bodies for a perfect fit.

Let's talk the rings. The top O-ring is for your preferred dildo and can be stretched to fit a dildo between 3.17cm to 5.08cm wide. The bottom O-ring is for your penis or packer, and also acts as a soft cock ring. This O-ring comes in two sizes, regular or magnum. Just double check the size of the bottom O-ring, to see which you would need. Both rings have two small flaps so the wearer can opt to have the dildo base against the skin or covered, and have the penis in or outside pouch.

Please have a look at the videos tab for how to choose your size, wear, and using with dildo's and prosthetics.

Why do people choose a Deuce strap-on harness to use? 

  • if you're experiencing erectile issues
  • wanting to try double penetration
  • continuing sex after a bio penis ejaculates
  • to continue sex between erections
  • trans men to wear it with their packer/penis
  • to experience the thrills of denial of pleasure in a kinky way
  • for serodiscordant couples
  • for people born with two bio penises on top of one another
  • wear as regular underwear because it's so comfy
  • and for swapping genders for cosplay

    If any of those few reasons resonate with you, it may be worth you picking one up today! It also comes with an attractive and lightweight storage pouch with two handy pockets, so if you're the travelling type, you're sorted!
