Mountain Hardwear M Airmesh™ Long Sleeve

A single layer can have a greater impact than you think. Our packable long-sleeve shirt offers the highest warmth-to-weight ratio of any fabric in our line, along with high breathability, comfortable thumb loops, and a secure zippered chest pocket for storing essentials. This unique active mesh construction is made from hollow, tubular fibers that quickly and efficiently absorb sweat—providing supportive insulation and heat shielding to keep you temperature-regulated from the trail to the lift and everywhere in between.
