Devil Horn Strap On Harness Red and Black

56.00 USD

A vegan leather strap on harness with two red devil horns at the hips, an open back, and three interchangeable O rings so it fits almost any dildo you already own.

Most strap on harnesses are built to disappear. This one is not. The front panel carries a creature eye emblem and a pair of curved red horns sit at the hip line, so the harness reads as part of the scene rather than as hardware you put on to get to the good part. If you are into the look, that matters more than any spec on the page.

Underneath the styling it is a serious harness. The back is open, which means the person wearing it can be penetrated at the same time, and it also keeps the whole thing cooler and easier to wear for a long session. A wide supportive strap across the back spreads the load instead of digging in, which is what lets it hold a heavy dildo without sagging forward.

Three O rings ship in the box at 1.25, 1.5 and 2 inches, so you are not stuck matching a single opening to whatever you buy later. Swapping one out takes a few seconds. The red and black dildo in these photos is our Flame Demon Dildo, sold separately.

Why this works

  • Three O rings at 1.25, 1.5 and 2 inches, so most dildo bases will fit without buying an adapter
  • Open back design lets the wearer be penetrated while wearing it
  • Wide back strap spreads weight, which is what keeps a heavy dildo from pulling the front panel down
  • Nickel free buckles and iron D rings, so it holds adjustment instead of creeping loose
  • Separate thigh straps stop the front panel from shifting side to side mid thrust
  • Wide 31 to 45 inch waist range with thigh straps to 23 inches
  • Red devil horns and a creature eye emblem, for people who want the harness to be part of the look

Care

Wipe the panel and straps down with a damp cloth and mild soap, then let it air dry completely before you put it away. Do not put vegan leather in a machine or soak it. The O rings are the only part that goes in water, and those wash with warm water and soap. Store it flat or hanging rather than folded, so the panel keeps its shape.

Use it for

Pegging, strap on play between partners of any gender, double penetration where the wearer is also being penetrated through the open back, and any scene where you want the harness itself to look like something.

FAQ

Does a dildo come with it?
No. This is the harness only. Every photo shows a dildo fitted so you can see how it sits, but nothing insertable is in the box. You choose your own, which is the point of the three O ring sizes. The one pictured is our Flame Demon Dildo.

How do I know if my dildo will fit?
Measure the shaft just above the base, at the narrowest point where the O ring will sit. If that measurement is close to 1.25, 1.5 or 2 inches, one of the included rings will work. A flared base is what holds it in place, so a suction cup base or a flat flared base is what you want.

What is the open back for?
Two things. It means the wearer can be penetrated at the same time, with a toy or a partner, and it also makes the harness far cooler and more comfortable than a full brief style over a long session.

Will it hold a heavy dildo?
Yes. The wide back strap and the thigh straps are there specifically to carry weight. A heavy dildo in a thin single strap harness pulls forward and droops. This one does not.

What waist sizes does it fit?
31 to 45 inches at the waist, with thigh straps that adjust up to 23 inches. Measure where the strap will actually sit, at the hip bone, rather than at your natural waist.

Is the vegan leather actually vegan?
Yes. It is PU, so no animal material is used anywhere in the panel or the straps, and the buckles are nickel free.

Is it discreet?
The harness itself is not, and it is not trying to be. All orders from The White Unicorn ship in a plain package, and the return label will read TWU or shipping department.
