Strap-On Harnesses

A strap on harness holds a dildo securely against the body for hands-free penetration. Our range includes adjustable strap harnesses, underwear-style briefs, and leather designs from SpareParts, Sportsheets, and Tantus, from $29. Most use an O-ring that fits any dildo with a flared base, and many come with interchangeable ring sizes.

Buying guide

How to choose a strap-on harness

A good harness feels stable, comfortable, and secure. Fit and the O-ring matter more than anything else.

01

Harness styles

  • Two-strap (jock) style: a strap goes around each thigh for more control and a snug fit.
  • Single-strap (thong) style: one strap between the legs, simpler but more likely to shift.
  • Underwear style: briefs with a built-in O-ring. These are comfortable for long wear, and a slim strapon harness brief works under jeans for packing.
02

Material

Nylon webbing is affordable and easy to adjust. Neoprene is soft and washable. A leather strap on harness looks classic and molds to the body over time but needs conditioning. Fabric briefs are usually machine washable, so check the care label. Vegan materials suit anyone avoiding animal products. Wide, padded straps spread pressure and feel better during longer sessions.

03

O-ring size and toy compatibility

Match the O-ring to your dildo base, measuring the base width if the listing does not state it. Silicone rings stretch, while metal rings are fixed but very secure. Many harnesses include several ring sizes. A double-ring harness holds two toys at once. Browse silicone dildos and vibrating dildos with flared bases that fit most rings.

04

Pegging and first-time use

A pegging harness is any harness that holds a toy steady for anal play. Choose a smaller, smooth silicone toy with a flared base, and use plenty of lube. Ready-made pegging kits include both pieces. For all-in-one designs, see strap-ons. Practice putting the harness on before the moment matters, so adjusting it feels easy.

FAQ

Strap-On Harnesses: common questions

Quick answers from our team. Need more help? Call 800-618-6053.

What is the best strap-on harness for beginners?
An adjustable two-strap harness with a stretchy O-ring is the easiest place to start. Thigh straps keep the toy steady and help control the angle, and adjustable sizing fits a wide range of bodies. Pair it with a medium silicone dildo that has a flared base.
Can you wear a strap-on harness under jeans?
Yes. Underwear-style harnesses are slim enough to wear under jeans or pants. Many people use them to hold a soft packer during the day, then swap in a firmer toy later. Choose a brief with a front O-ring and soft fabric that feels like regular underwear.
How do I know if a dildo will fit my harness?
Check that the dildo has a flared base, then compare the base diameter with the inner diameter of the O-ring. The shaft should pass through while the base stays behind the ring. Stretchy silicone rings fit a wider range of toys than fixed metal rings.
How do you clean a strap-on harness?
Fabric and neoprene harnesses can usually be hand or machine washed on a gentle cycle, but check the care label first. Wipe nylon webbing with soap and water. Clean leather with a damp cloth and condition it. Always wash the dildo separately and let everything dry fully.
