Patagonia's lightest-weight technical top wicks away moisture and dries fast for high-output days in temperatures ranging from cool to hot. These tees are Fair Trade Certified sewn and made with 52% recycled polyester and HeiQ Pure odour control for reliable freshness you can rely on for multi-day treks. Set-in sleeves and side vents offer enhanced movement, while a scoop neck gives a feminine-specific fit.
