This is a sleek harness for anyone looking for strap-on play. It can also be reversed to hold a toy inside someone, hands free! I bought this specifically for pegging, and it performed spectacularly. I had been using a cheap harness from a local store; using this was a dream comparatively. It's a very economical choice at under $30 and the whole thing was designed on functionality. Easy to use straps/o-rings/buckles, and it feels very tight.

The straps are made of nylon. Not the most comfortable of materials, but strong. They breath better than leather or PVC. The length of the straps is adjusted by the same type of buckles you'll find on backpack straps. This is wonderful! Simply pull on the strap to tighten, and pull up on the buckle to loosen. These come together to hold an o-ring, using very sturdy metal snaps. The base of the dildo sits against a soft leather patch that is comfortable and provides a smooth surface for it to rest against. Overall, I'm very impressed with the quality of the materials used.

By far, the double strap design is the way to go. Unlike g-string type harnesses, it provides a massive amount of control from the user. I could literally feel her shifting angles inside me as she teased my p-spot. The four straps hold the dildo tight against her pubic region and do not allow for any play in movement. I'm sold that double straps are the best design you can buy for a harness. The o-ring that it comes with is very strong and easily interchangeable using the snaps.
(Quick tip: If you need an o-ring quickly, head to an automotive parts store. Auto o-rings are very strong and a dime a dozen.)

The straps are very long, and I would imagine that they would fit a very large person, but are easily cinched down to a petite size. Since the straps are made of nylon you can easily get rid of excess length by snipping them and then slowly melting the frayed ends with a lighter.

This harness performed it's job with a spectacular gusto! The o-ring fit the dildo that I bought (Grrl Toyz Lilac Strap-on dong) perfectly snug. It is very easily and quickly tightened on her using the intuitive backpack-esque straps. (none of which slipped during my exquisite anal escapade)
It's comfortable enough that she even enjoys wearing it around the house. The harness puts the dildo right where a real penis would be. I couldn't find any position that was difficult, especially since the double strap gave her a great amount of control on the angle and position of the dildo.

It's easy to take care of since the leather just needs a bit of oil once a year. The nylon straps are synthetic, so they can not rot from moisture or lube. You can easily remove the leather patch for cleaning and throw everything else in the washing machine. Make sure that the leather is free of lubes and isn't bent or creased during storage.

It comes in a simple, cheap, cardstock box. Good; keeps my product cheap.
