When our Theo dildo harness by SpareParts HardWear arrived we knew immediately that this harness was different than other harnesses we have tried. We chose the Pink one which looks gorgeous on Mrs. Peg! Coupled with a jet black dildo, I could barely contain my excitement. The Theo harness isn't all about good looks, though; it is perfectly designed for pegging.


The Theo is constructed of high-quality, man-made material. This means the Theo has huge advantages over leather harnesses. Because there are no animal products, it is vegan-friendly. Second, it is water-friendly. Third, and most importantly, it is SUPER soft. The only hard things on this harness are buckles for adjusting the straps and pearlescent snaps. The Theo is designed, however, so these are kept far from your skin so you won't be pinched. If you have ever been pinched while cinching up a d-ring, you will definitely appreciate this feature!


Being waterproof is important for two reasons. First, it's a high-quality harness that can be worn in the shower. Playing in the shower is always fun. Being able to peg in the shower has opened a whole world of very hot opportunities. The second benefit to being waterproof is you can wash the Theo. This is especially important with a single strap design because of where that strap ends up. Leather just can't be cleaned as well as the Theo.


Theo also stands apart because of the way it's designed. It simply isn't designed like other harnesses. Expect a bit of a learning curve when you first pull this beauty out of the satin storage bag. It comes with instructions, but those aren't incredibly clear. We recommend taking a moment to watch the hot video on the SpareParts HardWear website. It sheds some light on how to don the Theo. Our next recommendation is trial and error. This was a very hot experience, because it involved a lot of experimentation, and allowed the anticipation to build. We did find that you need an extra set of hands to fit this the first time.


The Theo comes in two sizes: small and large. The Theo is incredibly adjustable. Thanks to the system of snaps, straps and Velcro, it will fit a wide variety of body types. It even comes with an extra strap to extend the thong strap. Our recommendation is that you play with fitting the Theo. We thought we had it fitted only to discover that by lowering the Theo on Mrs. Peg's hips, she achieved a more comfortable fit and a better pegging angle.


The Theo's “O-ring” remains a bit of a mystery. It is enclosed in fabric so I can't tell what it's made from. I can say it's some magical material, because it holds dildos with varying girths equally well. We've played with thick, thin and average dildos, and they all held well. Whatever is going on, it works great!

The dildo placement in the Theo is as good as it gets. Once properly adjusted, the Theo holds dildos directly on Mrs. Peg's pubic bone, which provides a natural look and feel. Mrs. Peg is able to control her pegging action easily with natural hip movements, which feel great on the receiving end.


The Theo has other great features worth mentioning. First, there's an innovative little pocket on the t-back. It's intended to be a condom pocket. However, it can hold any number of things including a sachet of lube, the key to a restraint, a vibe controller, or any other small necessity. The Theo's wide waist band is extremely comfortable, and looks incredibly sexy wrapped around Mrs. Peg's hips. There's also a pouch that the dildo is inserted through. This provides a cloth barrier between the dildo's base and the wearer. It's also suitable for packing as it gives you some place to stash your sac. Because the back of the pouch can be left open, it can also accommodate double-ended dildos.


When we first got the Theo, Mrs. Peg was a little put off by the thickness of the thong strap. She prefers single strap harnesses because of how they feel between her legs. This strap, however, took some getting used to because it's a little bulkier than she is used to. We have been using Theo for a while now and this is no longer an issue for her.


The Theo harness is an incredibly well-made and versatile harness that is especially well-suited for pegging. The high-quality materials have stood up to multiple uses without any real signs of wear and tear. Theo holds dildos well and in a comfortable position. While it took a little while to figure out how it best fit Mrs. Peg, that time was well spent. We love the look, feel and performance of our Theo harness.

SpareParts makes the most wonderful harnesses and the Theo is no exception. The Theo is, hands down, the best single-strap harness we have experienced. The only reason why we don't always you use this harness is Mrs. Peg doesn't always want to use a single-strap harnesses. If that's the case, we use Theo's kissing cousin, the Joque. So while the Theo may not be always be our go-to harness, we are always reaching for a SpareParts harness.

The harness has held up without complaint to regular washings and a lot of use. We could not be happier.
