Strap-ons Harnesses

Strap-On Harnesses and Strap-On Sets for Every Body

Strap-on harnesses let one partner wear a dildo or vibrator at the hips so they can penetrate with their body while their hands stay free. Our range covers harness-only designs to pair with a toy you already own, complete harness and dildo sets, vibrating and remote control strap-ons, hollow strap-ons, double-ended and strapless styles, and pegging kits. You will find adjustable belts, briefs, boxer styles and thigh harnesses in nylon, PU leather, vegan leather, latex and elastic. They suit couples of every gender and orientation. Check the waist range, O-ring or docking size and materials on each listing to find a secure, comfortable fit.

How Strap-Ons Work and Who They Suit

A strap-on has two parts: a harness that sits on the body and a toy that is held in place at the front. The harness spreads the toy's weight across your hips, so you can move naturally and focus on your partner. Strap-ons are used by lesbian and queer couples, by straight couples who enjoy pegging, by people who want to add a second point of penetration, and by anyone who wants to explore different roles in bed. For more shared-play ideas, see our sex toys for couples.

O-Rings, Docking Plates and Fixed Toys

Most harnesses hold the toy with an O-ring that the base of a dildo passes through. Many sets include several ring sizes, so you can fit toys of different widths. Some harnesses, such as the King Cock Elite and Pipedream Body Dock designs, use a docking plate that grips a suction cup base instead of a ring. Other sets come with a fixed toy that is built into the harness. Check which system a harness uses before pairing it with a dildo you already own.

Wearing Comfort and Fit

Harnesses come in belt styles with adjustable straps, brief and boxer styles that feel more like underwear, and thigh harnesses that hold a toy on the leg for riding. Adjustable belts usually suit the widest range of bodies, and some listings give a waist measurement range or include a waistband extension. Plus-size options are also available.

Types of Strap-On Harnesses and Sets

Harness-Only Designs

If you already own a dildo with a flared or suction cup base, a harness on its own gives you the most flexibility. Choose from adjustable nylon belts, padded PU leather and vegan leather harnesses, heavy-duty belts, velvet-lined styles and boxer brief harnesses that can also hold soft packers.

Harness and Dildo Sets

Ready-to-wear sets pair a harness with a matching dildo, so you know the two will fit together. Realistic dual-density dildos, bendable shafts and liquid silicone models from brands such as Rockarmy, Cock Miller, Harness Attraction and Pretty Love feature here. If you would like a different toy for your harness, browse our realistic dildos.

Vibrating and Remote Control Strap-Ons

Vibrating strap-ons add a motor to the dildo or to a pad that rests against the wearer. Some, such as Cyber Silicock sets, add remote control and an up-and-down thrusting motion, so either partner can change the settings without stopping. Check the power source, controls and water resistance on each listing.

Hollow Strap-Ons

Hollow strap-ons are worn over the penis, adding length and girth during partnered sex. They can be worn with or without an erection, and some include vibration. Look at the internal length and width as well as the outside dimensions to make sure the fit is comfortable.

Double-Ended and Strapless Strap-Ons

Double-ended strap-ons have an inner plug or shaft for the wearer and an outer shaft for their partner, so both feel penetration at once. Strapless strap-ons skip the harness: the wearer holds a shorter bulb inside with their pelvic muscles. These take a little practice. Our double-ended dildos collection has more shared-play options.

Pegging Kits and Double Dildo Harnesses

Pegging kits combine a harness with probes shaped for anal play, often with a gentle curve towards the prostate. A few harnesses hold two dildos at once for double penetration. If you are exploring prostate play, our prostate massagers are another option to try first.

How to Choose Strap-On Harnesses

• Fit: Check the waist range and whether straps adjust at the waist and thighs. Brief and boxer styles are often listed in set sizes or one size.
• Toy attachment: Note whether the harness uses an O-ring, several interchangeable rings or a docking plate, and match it to the base of your dildo.
• Materials: Nylon and elastic are light and easy to wash, PU and vegan leather feel more structured, and latex suits fetish wear. Check each listing if you have a latex allergy.
• Dildo size: In a set, compare the insertable length and width with what your partner is comfortable with. A smaller first toy is a sensible choice.
• Extras: Decide whether you want vibration, remote control, a hollow shaft or an internal plug for the wearer.

Safe and Comfortable Strap-On Play

Before You Start

• Talk it through: Agree on what you want to try, how deep and fast to go, and a clear word or signal to stop.
• Practise the fit: Put the harness on and adjust it before things get heated. It should feel secure without pinching or cutting in.
• Start with a smaller toy: Especially for first-time pegging or anal play, choose a slimmer dildo and build up over time.

During Play

• Use plenty of lubricant: If you are unsure, a water-based lubricant is usually the safest choice. Avoid silicone lubricant on silicone toys unless the maker says it is fine.
• Go slowly: The wearer cannot feel resistance in the same way as with a hand-held toy, so move gently and check in often.
• Anal use: Only use toys designed for anal play with a flared base. Stop if there is any pain. Our anal sex toys collection has smaller toys for warming up.
• Watch for chafing: Check the skin under straps during longer sessions and loosen them if needed.

Hygiene and Sharing

The NHS advises keeping sex toys clean and, if you share them, washing them between each use and putting a new condom on them each time. This matters when moving between partners or between anal and vaginal play. Read more in the NHS guidance on sex activities and risk.

Cleaning and Caring for Strap-On Harnesses

• Clean the toy after every use: Remove the dildo and wash it with warm water and mild, unscented soap or a toy cleaner, then dry it fully.
• Wash the harness by its material: Nylon and elastic harnesses can usually be hand-washed. Wipe PU and vegan leather with a damp cloth. Follow the care instructions on each listing.
• Look after latex: Rinse latex items, dry them thoroughly and store them away from oils, heat and direct sunlight.
• Protect electronics: Keep motors, remotes and charging ports dry unless the listing says they are waterproof.
• Store flat and separate: Keep the harness and toys in clean pouches, with silicone toys stored apart from other materials.
