The Arcteryx Alpha SL 30 backpack is the brand’s lightest alpine pack yet that focuses on technical capabilities without skimping on simply style. The pack weighs in at just 428-grams thanks to the ALUULA Graflyte material used in its construction, but comes in at stronger than steel by weight while also being completely waterproof. The pack is constructed with a thermoformed back panel alongside padded shoulder straps, dog bone attachments for tools and much more.

The Arcteryx Alpha SL 30 backpack is engineered with maximum durability and adaptability in mind, and is even easy to repair thanks to complimentary patch kits offered through the ReBIRD service centers. The pack is available now from the brand for $400.
