Alpha SL Jacket Men's is a shell jacket designed for alpine activity, built to be lightweight and packable while providing waterproof, windproof protection and breathability in harsh mountain conditions.
Pair it with men's hiking pants and a hiking fleece for alpine layering.
The Alpha SL Jacket provides exceptional durability, breathability, and waterproof protection against the very harshest alpine conditions, while staying so light and packable that carrying it on technical climbs and long mountain days is never a second thought. No excess, just pure function. And as the lightest GORE-TEX PRO shell ever made, it's a new benchmark in alpine minimalism.
What's been updated: The Alpha SL Jacket now features GORE-TEX PRO ePE with our propriety Hadron™ face fabric in an ultralight 20D weight, delivering the highest-performing waterproof, breathable protection while remaining free from intentionally added PFAS. The fully adjustable, helmet-compatible StormHood™ offers a precise fit with unobstructed upward and peripheral visibility. The addition of a low-profile RECCO® Reflector improves your searchability in emergency situations.
Lightweight, minimalist climbing and alpinism products that protect from alpine environments.
Climbing equipment designed for efficient movement and protection in alpine environments.
Waterproof, windproof and breathable textiles that offer fully protective environmental shelter.
Superlight materials and design, emphasizing light weight and packability over durablity.
Durable GORE-TEX PRO ePE and Hadron™ fabric is fully weatherproof.
Light and packable enough to pull out on any alpine climb.
The adjustable, helmet-compatible StormHood™ preserves visibility.
As GORE-TEX’s leading partner, we led the development of GORE-TEX PRO ePE: a stronger, thinner membrane with maximum durability. Our GORE-TEX PRO ePE shells have been rigorously designed and tested to keep you dry for seasons to come.
Our proprietary Hadron® fabric is engineered with a fine-gauge liquid crystal polymer (LCP) for abrasion resistance rivalling fabrics twice its weight
RECCO® reflectors can help ski patrollers and mountain rescue teams utilizing RECCO® detectors more quickly locate a lost or buried person.
The StormHood™ provides complete coverage with a unique design that adjusts to pivot with your head and maximize your field of view.
Our trimmer fit is patterned to stay close to the body through the chest, waist, hip, and thigh. Its low profile eliminates bulk, moves with the body, and fits comfortably over first layers or under outer layers.
