Combining the breathability and mobility of a softshell with the warmth of an insulated midlayer, the versatile Proton LT might just be a quiver killer for alpinists, backcountry skiers and cool weather climbers. Lightweight Coreloft™ Continuous fill provides enough insulation for moderate output activities in low temps, and breathes well to prevent vapour accumulation and overheating. As you'd expect from Arc'teryx, this hoody is beautifully designed and constructed, with articulated arms and an ergonomic, helmet-compatible hood to meet the needs of mountain athletes in tough conditions.
