Tell me more about the fit

Our Performance Innerwear is meant to fit snugly on the body. If you prefer a looser fit, we recommend sizing up. If it feels just a little tight and you aren't sure if the next size up would be better, then we recommend wearing and washing a few times to see if it breaks in to your liking before exchanging it for another size.

Will it stretch out?

Not really. Our Performance Innerwear does give a bit with wear, but instead of becoming loose, it will mold to your body more over time.

50% brief, 50% short, 100% incredible. Our Essential Boyshort brings more coverage than the Hipster, making it your go-to for lounging, lunging, layering, or taking a spontaneous swim. Under a dress or your ski bibs, it shape-shifts as effortlessly as you do.

Our seamless Merino and elastic-free waistband mean no digging, no rolling, no adjusting—ever.  Finished hem leg openings move with you from early-morning miles to end-of-day exhale. So buttery-soft, you’ll forget you’re wearing it... until you realize you never want to take it off.

Bonus: Our proprietary GLDNspun™ technology is crafted with ZQ, RWS, and Woolmark-certified Merino, and OEKO-TEX® 100-certified fibers–that means it is sustainable—free from BPA, PFAs, and other toxic “forever chemicals.”

Double Bonus: Our Boyshorts can be worn two ways: snug around the hips or pulled up just below the belly button for a higher-waisted fit and more tummy coverage.

PERFORMANCE WITHOUT COMPROMISE

Designed for superior performance and maximum comfort—it all starts with Merino wool. Super-soft, ultra-fine Merino wicks sweat to keep you dry, fresh, and funk-free. The natural crimp of its fiber traps air so you stay cool when things heat up and keep warm when there’s a chill.
