Ultra 2 Vac-U-Lock Harness

Strap In to Better Sex.

No frills. No nonsense. Just a solid harness that gets the job done.

Ready to take things a little deeper? Relationships may be complicated, but penetration doesn’t have to be. The Ultra 2 Vac-U-Lock Harness has been helping people strap up with confidence for over 20 years — and it’s still one of the most popular (and affordable) options in the Vac-U-Lock lineup for a reason.

This beginner-friendly harness is made from durable PVC and adjusts up to a 53" waist, making it easy to fit, easy to use, and easy to come back to. It’s unisex by design and works across genders, bodies, and dynamics — whether you’re gearing up for lesbian sex, pegging your male partner, or adding a little extra horsepower to straight sex.

Because there’s room for the penis and balls to hang free, the Ultra 2 can also be used by men for double-penetrative sex with female partners, or as a reliable backup for anyone dealing with erectile dysfunction. Simple, practical, and refreshingly honest about what people actually use strap-ons for.

Snap in the Vac-U-Lock attachment of your choice and you’re good to go. Probing, pegging, thrusting — whatever the night calls for. There’s always a learning curve the first time you wear a strap-on, but practice makes things smoother fast. Listen to your partner, take your time, and use plenty of lube. You’ll figure it out.

How To Use It

Insert the red Vac-U-Lock plug through the opening in the harness and snap it firmly into place. Align the hole on the back of your Vac-U-Lock attachment with the plug and press until it locks. That’s it — no guesswork, no surprises.

After the Afterglow

Wipe down the harness after use with mild soap or toy cleaner, rinse with water, and wipe dry. Easy upkeep for something you’ll probably reach for again.
