When you're climbing above 6,000 meters in a howling blizzard, the last thing you want to be worrying about is your gear. The Montane Cerro Men's Hooded Down Jacket is certified worry free, with a highly water repellent Pertex Endurance nylon ripstop shell and water resistant HypderDRY 750 fill down to keep you warm when the wind's whipping, the snow's blowing, and your eyelids are threatening to freeze shut. While the Pertex keeps water off your back and your down warm and lofty, the Peaq Down downproof lining prevents feathers from leaking and sweat from building up, which can spell freezing disaster as soon as you stop moving. Montana designed the Cerro explicitly for alpine climbing and mountaineering, so it has thoughtful features meant to keep you comfortable when you're focused on moving up. The sleeves, for example, are articulated for mobility and engineered to be raised without lifting the hem of the jacket, so you can reach up without exposing your waist to the elements. An internal waist drawcord, adjustable hem, and hook and loop cuffs don't provide any entryways for bone chilling drafts and skin burning spindrift, and the insulated, adjustable, and helmet compatible hood stows away so it doesn't get blown into your face when you're trying to see the route ahead of you. Montane finished the Cerro off with strategically placed pockets and glove friendly zipper pulls, and made sure the front zipper and hem cord locks were low profile for comfort under a harness.
