SparePart’s Tomboii Brief is one of their best products designed and enjoyed by the LGBTQIA+ community. This sporty, comfortable brief slips on and stays on, no matter how you choose to play: strap-ons, packers, double dildos, you name it—the Spareparts Tomboii can handle it! 😉 Complete with a stretchy o-ring and moisture-wicking fabric, you’ll find this harness will stick around no matter what you put it through.

Available in red or black and sizes between XS and 5X, we’re happy to report there’s a Tomboii that will match your style. Two built-in panels create a barrier between the base of packers or dildos and your skin. These clever pockets can hold a bullet vibrator or add extra room for grinding bases. Did we mention all Spareparts Tomboii harnesses are safe to throw in the washer machine? 🥳

Adam ★★★★★ Oct 13, 2026

I was worried a brief-style harness would shift around, but the wide waistband keeps everything locked in place even when things get vigorous. The fabric is soft enough to wear for a while without chafing, which I didn't expect from something this sturdy.

I was skeptical at first, but this brief-style harness actually stays locked in place during play. The sporty cut is comfortable under clothes too.

John ★★★★☆ Oct 12, 2026

The sporty cut sits higher on the hip than I expected, which actually keeps everything in place during play. Only gripe is the waistband rolls a bit after a few hours, but the O-ring holds snug and it slips on way faster than my old strap setup.
