The Best Fabric for Active Lifestyles

Airmotion™ is Ultralight

Our Airmotion Sport trunks weigh just over an ounce, offering you unparalleled comfort without the bulk. Say goodbye to heavy, uncomfortable underwear and embrace the freedom of featherlight fabric.

Airmotion is Ultrathin:

Perfect for ultralight travel and hiking, our underwear takes up minimal space in your backpack or suitcase. Don’t compromise on comfort when space is at a premium. So thin they can be worn under bike shorts.

Airmotion performs

Our innovative Airmotion fabric technology ensures quick-drying and breathable underwear that stands up to the rigors of active lifestyles. Stay fresh and cool even during strenuous activities

Airmotion is built to last

While our underwear is incredibly lightweight, we haven’t compromised on quality. We guarantee Airmotion against defects for life. If you ever experience a defect just email us for a refund or a new pair.

Size and Cut Details

Your cut choice depends on daily wear. The versatile Standard Cut is popular, fitting all body types and comfort needs. The snug Trunk provides robust support and lift. For a middle ground, size up on the Trunk cut.

Get the standard if you prefer a more traditional boxer brief and like more leg coverage, but still want good support.

Get the trunk if you prefer a lower rise, shorter legs, and more support and enhancement. It’s a more snug fit.

Because we obsessed over the details to get the fit just right. Our underwear are designed to be a little snug but delightfully comfortable, so you get the support you need without pinching or riding up.

Our Magical Pouch design gently lifts your package to prevent skin on skin contact, chafing and the need to constantly adjust. Once you try our underwear you’ll never want to go back to normal underwear.
