Backed by a 100% satisfaction guarantee, you can trust that if you don't love it, you'll be taken care of. Plus, if you don't trust us you should trust the hundreds of positive reviews all over the web and professional athletes wearing and talking about our products. 

Superior Materials

Focus on Comfort

Obviously protection matters. But so does your comfort. The reason so many guys don't wear a cup system is because it's simply uncomfortable. We designed a cup and corresponding short system that is so comfortable you'll forget you're wearing it.

Designed By Experts

Designed by a team of award winning designers, Stanford University engineers, and most importantly, athletes practicing in the sport testing the products day in and day out.

Great product!

Right out of the box you can tell that the shorts and cup are high quality. The cup is comfortable to wear during sparring. Having the jock strap sewn into the shorts is very convenient. Definitely recommend. If the performance shorts were made with different colors I would definitely buy additional pairs.

This company!!!

After accidentally ordering the wrong size, Stephanie with customer service was extra helpful. Helped me exchange them without missing a beat.
Also, I still managed to order something different than intended BUT my husband likes them even more than the original product I was planning to purchase. He says they’re so comfortable and loves the length of them.

Great fit

The performance shorts are a great fit for workouts in the weight room and running. I will try them for biking when all this smoke clears in Northern California. They are secure enough to where I can use them for umpiring and playing hard ball. 💯% recommend. RD

Performance Short Review

These shorts are easily the most comfortable and versatile shorts ever. I've used them for No-Gi Jiu Jitsu and for functional fitness workouts. They moved effortlessly with my body and didn't need readjustment at all. They have instantly become my most favorite pair of shorts.
