ME Aerotherm Vest

Made from an ultralight double-weave softshell fabric with a micro-grid backing that wicks moisture, this versatile windproof layer helps regulate body temperature and humidity during uphill efforts, and then keeps your core warm on exposed summits and ridges. It dries quickly after a climb and is a vest you can keep on in changeable weather conditions, whether you're climbing, running, or hiking.

The semi-elasticated hem and armholes are comfortable and help keep out drafts, while zippered hand pockets and a chest pocket allow you to store essentials. The vest packs neatly into its own pocket with two carrying loops, making it easy to transport in a backpack or on a harness, making it an easy item to take with you on mountain days.
