The North Face Men's Alta Vista Jacket is a 2.5L shell for hiking. Throw it on if the day starts rough, or tuck it away into its own pocket for easy packing into your pack. It's quick-deploying when the weather turns, providing waterproof, breathable protection. The hood adjusts to bring it in close, preventing wind from shoving it back and rain from hitting your face. Whenever the warm summer rains have your body heating up, just open the pit zips to release that heat without exposing your front to the rain.
