Minimal and lightweight, the Alpha SL Anorak from Arc’teryx delivers unrivaled durability and resistance, despite being the brand’s finest piece. It’s crafted from 3L GORE-TEX and Hadron™ fabric – a gridded face fabric engineered with liquid crystal polymer ripstop – which provides weather-resistant protection and resistance rivalling fabrics twice its weight. Other features include a helmet compatible StormHood™ and the brand’s signature Archaeopteryx embroidered above the chest pocket.
