Howling snowstorms, wind-blasted summits, and extreme winter conditions have nothing on the bombproof construction, moisture-shedding ability, and breathable performance of the Marmot Men's Alpinist Jacket. This top-shelf shell represents Marmot's 40-plus years of design expertise in creating outerwear to excel in the planet's harshest environments. It sports top-of-the-line three-layer Gore-Tex Pro fabric for exceptional waterproofing and breathability, a lightweight feel, and bombproof durability. Counted on by professional mountain guides and hardcore backcountry enthusiasts, Gore-Tex Pro offers the most reliable protection available from the worst weather winter has to offer. It's backed up by fully taped seams to prevent any moisture from seeping in through the cracks. But this jacket's much more than just its fabric. Its helmet-compatible hood has a laminated wire brim that shields your face from howling winds and driving snow while still allowing you to see clearly. The DriClime-lined chin guard pulls moisture away from your face when you're perspiring and breathing heavily, helping you feel more comfortable and less clammy. Underarm vents open up to release built-up heat and perspiration from intense skiing or climbing. Napoleon chest pockets stash your must-have items, and the waistbelt-friendly Pack Pockets offer easy-access to accessories when you're carrying a backcountry pack. In addition, the jacket's Angel-Wing Movement and athletic fit grant you full mobility for skiing, riding, and climbing.
