The Arc'teryx Alpha SL Hybrid Jacket is a super lightweight, compressible and waterproof jacket. With the use of two different GORE-TEX® textiles, the jacket has increased durability without unnecessary weight. The Alpha SL Hybrid Jacket is ideal for active rain wear thanks to its high breathability. So if you're hiking or climbing and an unexpected storm hits, rest easy knowing that you're protected from just about anything Mother Nature can throw at you.
2.5L GORE-TEX® PacLite® – Engineered specifically to be light, packable and more breathable than other fabrics
GORE-TEX® 3L – 3-Layer laminate fabric in the shoulders and underarm gussets for extra durability and breathability
GORE-TEX – Guaranteed to Keep You Dry. The GORE-TEX membrane is an extremely thin layer of expanded polytetrafluoroethylene (ePTFE). It has over 9 billion pores per square inch, large enough to let water vapor exit but small enough to prevent liquid water from entering.
Gusseted underarms for added durability
Athletic fit
Two zippered hand pockets
Underarm pit zips
Laminated watertight zippers
Helmet compatible Storm Hood with volume adjustability
Laminated die-cut rip and stick cuff adjusters reduce bulk and won't catch or tear off
