The Patagonia Women's Maipo Tank is a versatile, performance-oriented top designed for all-day comfort during climbing, hiking, or travel. Crafted from 81% NetPlus postconsumer recycled nylon and 19% spandex, it offers soft, lightweight stretch with moisture-wicking and odor-controlling properties. The narrow racerback and low, contoured armholes provide full mobility for high-intensity movement. A built-in, low-impact bra gives comfortable support on its own or can be paired with additional sports bras. Smooth seams and a hip-length cut reduce chafing and keep the tank in place under harnesses or backpacks. Made in a Fair Trade Certified(TM) factory, this tank blends sustainability, comfort, and functionality.
