The Arc'teryx Alpha Jacket pairs GORE-TEX PRO ePE with 50D Hadron™ face fabric for the right balance of waterproof-breathable performance and abrasion resistance. Built for climbers and skiers who need reliable alpine protection that performs through any storm without adding unnecessary grams, this jacket proves that going light doesn't mean compromising on the features that matter when conditions turn serious.
Body – 40d x70d recycled nylon plain weave with PU Membrane
Contrast – 20D Hadron™ 94% Nylon / 6% Polyarylate with ePE & PU Membrane
GORE-TEX PRO ePE – GORE-TEX ePE technology is the most innovative waterproof protection yet. Free of PFAS chemicals, the ePE membrane has a much lower environmental impact compared with membranes of the past. Even better: GORE-TEX ePE is half the thickness and thus lighter weight — which means Arc’teryx, and now you, can do more with less.
