WHAT CLIENTS SAY
Game changer!
I've always worn regular cotton boxers and these fit/feel so much better! I'll never go back... They don't bunch up when I'm working out, feel soft and flexible, have enough room and aren't restrictive for my package AND I can wear these and be comfortable (and have support) while playing sports.

The search for the perfect underwear is over!
I’ve tried a ton of athletic underwear, and let me tell you—these are the GOAT! They’re crazy comfy, stay in place no matter what, and keep everything cool and dry (seriously, no bat wing here!). Whether I’m weightlifting, biking, golfing, or crushing it at other sports, they’ve got my back. Once you try these, there’s no going back to anything else. Total game-changer!

Comfy and Supportive
I have been wearing the Core Active Boxer Briefs for a few months. I use them mostly for jiu jitsu. The briefs had held up through many training sessions and they still feel like new. I will be purchasing more to be used as my primary support briefs.
