Three Fabric Choices
18-Hour Jersey & AIRKNITx & Silver
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.
Silver is blended with antimicrobial Silver XT2®, a material used by NASA.
“Honestly - been wearing these trunks for going on 7 or 8 years, which also means they last! Nothing fits so well.”
“I am a new lover of the trunk. I often find boxer briefs rolling when I'm in slim jeans or work clothes. The trunk is the new boxer brief.”
“I’m so happy I decided to try them after scrolling past them on fb many times. I’m so impressed with the fit and feel. Definitely worth the price.”
