From overcast spring hiking to fast-paced tours in the backcountry, the Patagonia Nano-Air Light Hybrid Hooded Jacket is there for breathable warmth and performance stretch. The hood and body keep you warm when the weather refuses to cooperate, while breathable mesh panels at the sides and back vent out excess heat as you're hiking to the next peak. The entire jacket incorporates mechanical stretch so it's easy to scramble a rock race or dig through your gear bag, and the durable water repellent finish keeps brief showers from forcing your shell to come out of hiding.
