Two Fabric Choices
18-Hour Jersey & AIRKNITx
Better underwear is softer with just the right amount of freedom and support. We engineered our own fabric and spent over 10,000 hours to make sure our underwear is more comfortable for you.
18-Hour Jersey is the softest underwear you’ve ever worn.
AIRKNITx is lightweight, breathable, and keeps you fresh all day long.
“After 25+ years of boxer briefs I decided to try briefs again and these are fantastic. Comfortable waistband, fabric that I can wear anywhere.”
“Like butta. Possibly the most comfortable brief I’ve ever owned. And I own A LOT.”
“These are the most comfortable (and surprisingly sexy) briefs I've ever worn. They are lightweight but good at moisture wicking.”
Try On Guarantee
If you don't love the first pair of underwear, we'll send you a different pair, or issue you a full refund - no return required.
