The Mammut Treeline HS Thermo Hooded Jacket wraps reclaimed down insulation in a GORE-TEX ePE shell, so it blocks wind and rain on a commute the same way it would on a weekend hike. The down keeps us warm when temperatures drop, while the waterproof, windproof outer means a downpour or a raw wind doesn't cut the walk short. A snap-flap storm guard, adjustable cuffs, and a drawstring hem seal out cold air at every edge. What Our Gearhead(R) Experts Are Saying:"I wore this through a sleeting commute that would have soaked through anything else in my closet, and I stayed warm and completely dry the whole walk. That's the jacket that replaced my umbrella."
