Patagonia Maipo Tank Top

Whether you're bouldering in the desert, setting up camp, or grinding through a multi-pitch climb, the Patagonia Maipo Tank is your go-to for all-day comfort and performance. Designed with feedback from real climbers, it features a soft, stretchy fabric blend of 81% NetPlus® recycled nylon—made from reclaimed fishing nets—and 19% spandex for freedom of movement. The miDori™ bioSoft treatment enhances moisture-wicking and softness, while HeiQ® Mint controls odor on long, sweaty days.

A built-in bra offers low-impact support and layers smoothly with a sports bra for extra hold. The racerback design, low-profile seams, and contoured armholes keep you moving freely, and the hip-length fit stays put under a harness. Made in a Fair Trade Certified™ factory, this tank isn’t just good for your adventures—it’s good for the planet too.

Best use: Climbing, hiking, car camping, and warm-weather adventures that call for unrestricted comfort.
