Arc'teryx Alpha SL Jacket is a shell garment developed for demanding alpine conditions where low weight, maximum protection and high breathability are essential. The jacket is made from GORE-TEX PRO ePE – the lightest GORE-TEX PRO material available – and sets a new standard for minimalist mountain equipment. It combines ultralight construction with impressive durability, keeping you dry and protected in everything from strong winds to intense precipitation. The Hadron™ face fabric contributes additional robustness without increasing weight, making the jacket reliable on technical climbing routes and long days in the high mountains.

The streamlined design focuses exclusively on functional details. The StormHood™ provides full coverage and is helmet-compatible without restricting the field of vision, and the cuffs can be easily adjusted with Velcro® to keep out wind and weather. A water-resistant, laminated zip pocket on the chest offers secure storage for small items. The jacket has a back length of 78 cm in size M, with variation between sizes for an optimal fit.

The Alpha SL Jacket is treated with a PFAS-free FC0 DWR finish that repels moisture while meeting strict bluesign® requirements. Both the face fabric and lining are dope-dyed to reduce environmental impact. An integrated RECCO® reflector provides increased safety in emergency situations.

With a combination of waterproofing, breathability and durability in an extremely light and packable construction, the Alpha SL Jacket is made for alpinists who demand maximum performance without unnecessary details.
