ME Aerotherm Vest
Made from an ultralight double-weave softshell fabric with a micro-grid fleece backer that wicks moisture, this versatile windproof layer helps regulate body temperature and moisture during uphill efforts, 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, whether you're climbing, running, or hiking.
The semi-elasticated hem and armholes are comfortable and help keep drafts out, while zippered hand pockets and a chest pocket allow you to stash essentials. The vest packs neatly into its own pocket with two carrying loops, for easy transport on a pack or harness, making it an easy piece to take with you on mountain days.
