Breathable and stretchy with excellent protection from high altitude weather, the Mountain Equipment Women's Arclight Pants are ideal for high aerobic, high altitude winter pursuits. Built primarily for ski mountaineering, the Arclight Pants fuse breathability with bomb proof protection that will get you to your objective and down your line with finesse. Polartec Neoshell provides next level breathability so you stay dry on the inside and out. The stretch softshell fabric makes technical ascents a comfortable affair, while the active fit and articulated knees provide a slim fit that won't hang up on your gear or prevent layering underneath. Two zippered vents on the outer thighs allow for quick cool downs on those thigh burning switchbacks, and two lower leg zips from the cuff to knee make adjustments to your boots during transitions quick and easy. The gusseted ankle can be cranked down around whichever boots you're wearing to seal out snow, and the reinforced kick strips keep your pants intact when confronted with crampons and finely tuned ski edges. To keep things simple, the Arlights are equipped with two pockets located at the thigh and rear both are zippered utilizing YKK Aquaguard zippers to seal out snow and water.
