Stylish and sustainably made, the Mammut Alto Light HS Hooded Jacket keeps us dry when we're hiking the trail or wandering the urban jungle. Mammut's 2-layer hardshell is waterproof, windproof, and breathable, sealing out the elements while letting moisture vapor escape if we start to run warm. This jacket also features eco-certified, recycled materials, a PFC-free durable water repellent, and solution-dyed fabric to reduce our environmental impact.
