Discover the ultimate comfort in our SeamFree Collection—whether you’re setting out for weeks of travel or just looking for comfy underwear 365. We’ve spent over 20 years perfecting the art of travel underwear—that’s where the SeamFree Collection comes in. Knit with a durable jacquard nylon blend, it’s naturally breathable and seam-free, so it won’t bind or chafe, even when layered or under a backpack hipbelt. The SeamFree Collection is incredibly lightweight, breathable, and quick-drying to keep your cool in steamy, open-air tropical markets or on long-haul, hemisphere-hopping flights. It wicks moisture from your skin so you stay dry and comfortable, and it's quick and easy to wash and dry in a hotel sink or mountain stream. The waistband lies flat and the soft binding on the leg opening won’t chafe or creep. Plus, with HeiQ Mint™ for natural odor management, they’re engineered for long adventures.
