Under Armour Men&s ColdGear Reactor Hooded Jacket

Staying warm isn't a problem when you're hiking up a steep trail or moving at a quick clip across rolling terrain, but you're going to cool down quick once you stop to rest. Before that sweat has time to cool, quickly pull the Under Armour Men's Coldgear Reactor Hooded Jacket from you backpack and let its water-resistant synthetic fill trap body heat before you start to feel the chill. The jacket's stowable design packs away easily in a backpack, and its slim fit layers comfortably under a waterproof shell when high winds and heavy rains slow your pace as you descend back to the trailhead.
