What is a jock-style strap-on harness? A jock-style harness has a waistband and two straps that run under the buttocks, one per side, like a jockstrap. A traditional T-back design instead runs a single strap between the cheeks, which some wearers find irritating. The jock layout leaves the rear open and spreads the pull across the hips. On the Londyn, a soft fabric front panel sits against the body like underwear and holds the dildo in a stretchy O-ring.
Londyn harness: fits like underwear, holds like a harness
The Londyn is a black jock-style strap-on harness from the Thinz line by Curve Toys. Its front panel is soft fabric that shapes to the body the way underwear does. A stretchy waistband and two stretchy bum straps adjust to fit many body sizes, up to a 60 inch waist, and keep the harness steady during vigorous thrusting.
The dildo passes through a stretchy O-ring hole in the front panel, which accepts a wide range of girths. The harness is made from spandex, nylon, elastic and silicone, is vegan-friendly and can go in the washing machine. A dildo is not included.
Best for: A fit for wearers who dislike a strap between the cheeks, for couples who want a harness that looks like clothing, and for anyone who needs a wide size range. Pair it with a dildo that has a flared or suction cup base.

How to use
Loosen the waistband and both bum straps. Push your dildo through the O-ring from the inside of the front panel, so its base ends up flat between the panel and your body. Step into the harness like a pair of briefs and pull it up to your hips. Tighten the waistband first, then each bum strap, until the dildo stays put when you move your hips. It should feel snug but not dig in. Apply a lubricant that suits the dildo's material before use, and retighten the straps if things loosen.
Care
- Remove the dildo before washing the harness.
- The harness is machine washable; a gentle cycle is kind to elastic.
- Let it air dry fully before storing.
- Wash the dildo separately, following its own care instructions.
- Store it flat or folded, away from heat.

Frequently asked questions
What size waist does the Londyn fit?
The distributor states that it fits up to a 60 inch waist circumference. The waistband and both bum straps are stretchy and adjustable, so one harness covers a wide range of body sizes.
Which dildos fit the O-ring?
The O-ring hole is stretchy and is described as compatible with a wide range of dildo girths. Choose a dildo with a flared or suction cup base that is wider than the shaft, so the base stays behind the ring.
Does it come with a dildo?
No. The dildo is sold separately. The harness is only the wearable part: waistband, bum straps, front panel and O-ring. Any harness-compatible dildo with a suitable base can be used with it.
How is it different from a T-back harness?
A T-back harness has one strap that runs between the buttocks. The Londyn uses two straps that pass under the cheeks instead, which avoids that irritation and leaves the wearer's rear uncovered.
How do I clean it?
It is machine washable. Take the dildo out first and wash that by hand. Let the harness dry in the air before you put it away, since heat is hard on elastic.
