The Mountain Hardwear Airmesh™ Long Sleeve Top – Men’s is a do-everything, go-anywhere midlayer built for high motion in cold conditions. Packing the highest warmth-to-weight ratio in the Mountain Hardwear lineup, this uniquely engineered piece uses a hollow-core mesh fabric that traps heat, dries fast, and breathes continuously—keeping you balanced whether you’re powering uphill, settling into camp, or transitioning lift laps. Soft thumbholes, a left-chest zip pocket, and a smooth silhouette make it easy to wear solo or under a shell, while a reversible construction unlocks two temperature modes: high insulation one way, increased airflow the other. From winter running to mountaineering objectives, this ultralight layer pulls its weight far beyond what meets the eye.
