SHOP AIRKNITX

Engineered for maximum breathability and infused with 4-way stretch, our exclusive Airknit Technology promotes high impact performance with lightweight dry comfort. Learn more.

SHOP 18-HOUR JERSEY

A proprietary blend of cotton, beech wood modal, and Lycra®, this fabric rests for 18 hours before it's cut. The result is a softer and more consistent fit. Learn more.

SHOP SILVER

Silver particles naturally destroy odor-causing bacteria. We added Pima cotton to keep you cool and comfortable all day long. Learn more.

“When I was first considering these I read a review from someone who said he was going to replace all his old underwear with AIRKNITS. I thought this was a little bit ridiculous. Now I think I will eventually do the same over time. I would wear these every day if I had enough of them. They are that much more comfortable than everything else.”

RON

“My husband will only wear these boxers. He says they keep him from not sweating and the wicking is the best and feels like you're wearing nothing.”

DODIE

“Apparently I have been living my life with the wrong underwear. The fit. The breath-ability. The POUCH. I mean... I'm cool, comfortable, and now supported by more than my overbearing mother. I'm happy to start my new life with Mack Weldon.”
