The Women's Patagonia Maipo Tank Top is a soft, lightweight, and fast-drying top made with 81% NetPlus post-consumer recycled nylon and 19% spandex knit, featuring miDori bioSoft for added wicking and softness along with HeiQ Mint odor control. Designed with a narrow racerback and low, contoured armholes for unrestricted movement, it includes a built-in bra that provides comfortable, compressive, low-impact support and also layers well with sports bras. A subtle scooped V-neck balances coverage with ventilation, smooth seams help minimize chafing, and the hip-length design sits comfortably under a harness.
