Spareparts Tomboi Harness

Regular price $116.00

We've been searching for the perfect underwear harness since we first opened our doors back in the nineties, but until SpareParts launched the Tomboi and Sasha harnesses, we were skeptical that such a thing could even exist. Ever the perfectionists, the folks at SpareParts have come up with a harness that is incredibly durable, comfortable, and makes harness play easier than ever! Machine-washable (but you might want to hang to dry), the Tomboi fits just like briefs under clothes, and even has a strap to hold your packer in place for those times when your piece is more about presentation than performance.

Spare Parts harnesses are made in a sweatshop-free, fair wage environment in the USA, and much more durable and better made than other similar looking harnesses (we're looking at you rodeoh!)

Made of 77% nylon, 23% spandex. Comes with mesh bag for storage and washing.

Double check sizing

I did a TON of researcher before buying a brief style harness. This is the one I landed on and I am glad I purchased it. However, I did measure myself and somehow still ended up with one that was WAY Too big. Obviously I can't return it, which is very unfortunate, so I tried to see it smaller. Did not work. So make sure you check. Do not size up. Stay on the smaller end of your sizing and if you are between sizes choose the size down. Super well made though! Look forward to trying it when it fits property.

All the difference

I started with a leather harness. It was fun, but as a bigger woman, I found that it didn’t really meet my needs. Because I am curvy and soft, it had hard keeping the harness right enough I also felt self conscious of how it made me look (muffin top ;) these briefs totally fixed that problem! Although there is less access to me, where there is a will- there is a way. They gave me better control and felt much more comfortable and removed any nagging negative self talk. A win for sure! (Thanks to the reviews I knew to buy a size larger than you think you will need)


Snug fit but comfortable and easy to use.

Works great. Make sure to double check size

Works great. Make sure to double check size

I don't regret buying it though, the material is comfortable, and washable.

I bought the large but i wish I had bought the XL, my hips are a 40 and I thought i'd be okay, but it's a bit too tight. Works, but I wouldn't wear it all day. It's sturdy enough built that I think an XL would still hold everything in place. I don't regret buying it though, the material is comfortable, and washable.
