Mountain Equipment Aerotherm Jacket - Men's Blue Nights, L

From Backcountry

What Our Gearhead® Experts Are Saying: "This is one of my favorite layers for high-output days. It blocks wind incredibly well without overheating, dries fast after hard climbs, and layers cleanly under a shell when conditions turn. I reach for it constantly for trail runs, fast hikes, and scrambles." We rely on the Aerotherm Jacket when the day calls for speed, movement, and adaptability. Built by Mountain Equipment for fast-paced mountain travel, this lightweight layer balances wind protection, breathability, and just enough warmth to stay comfortable through variable conditions.
