Vac-u-lock Dildo

Vac-U-Lock by Doc Johnson is the world’s first and only patented harness system. Unlike most strap-on’s which require an O-ring set up, Vac-U-Lock strap-ons feature a unique plug system which securely holds your attachment in place for penetrative fun. Vac-U-Lock Dildos are compatible with the Vac-U-Lock Strap-On harnesses, which open up a whole new world of strap-on sex possibilities due to the design’s versatility.

Choose a Vac-u-Lock harness with a plug, then you can choose any Vac-u-Lock compatible dildo to attach to the plug and harness, no matter the size or the girth of the attachment. You’ll never need to worry about whether or not a dildo will fit your harness ever again!
