The unpredictable high alpine requires weather protection, and when we’re moving fast and light above the treeline, we’re bringing along the Mountain Equipment Aerofoil Full Zip Jacket as shelter from the elements. Made to block wind without slowing you down, this durable stretch soft shell jacket has the features you need with no frills. The hem and cuffs seal out the chill while the close-fitting hood eliminates bulk while blocking the elements. When the sun comes out, the whole thing zips into its own pocket with carry loops so you can clip it to your pack and keep moving.
