Best underwear for sports

My husband loves these. He uses them for gym workouts and says the breathable mesh panels on the backside and between the legs are a game-changer. The support and comfort are like no other underwear he’s worn previously.

Good product, not good service

The actual product is good and I think I’d really like them. There are two issues: 1) I apparently need a smaller size than what I ordered. So I followed the return/exchange instructions but never heard back from the company. So I’m stuck with underwear that is too big. 2) the pouch in front doesn’t contain everything where it’s supposed to stay. Was hopeful, now disappointed.

Money back guarantee

Love them, or we'll refund or exchange your first order.
