DESC: No excess features, with everything you need and nothing you don't, the durable, dependable, and lightweight Arc'teryx Alpha LT Jacket for Men is just 12.9 oz of storm fending protection. Designed for fast alpine adventures, the Alpha LT is constructed from GORE-TEX Pro Shell 3L making it extremely waterproof, snow-shedding, windproof, breathable, lightweight, compressible, and packable. Its redesigned Speed Hood covers your noggin in a flash, WaterTight zippers seal the worst of winter, and its Arcteryx HemLock keeps the jacket under your harness as you place your next piece of protection. Don't be fooled by the weight of the Alpha LT, the supple GORE-TEX Pro may be light but it's just as waterproof and much more breathable than its heavyweight counterparts. Easily an everyday jacket, the Alpha LT is just the right weight a shell should be. The zippers are extremely water resistant, and the Napoleon pocket placement is perfect if you are using it with a harness, not to mention the foam inserts.
