My peeps in the market for a lightweight Gore-Tex Pro Shell jacket should probably stop looking. You've found the Arc'teryx Alpha Jackets. The Arc'teryx Alpha SL, Alpha LT, and Alpha SV offer complete waterproof protection for trekking, ice climbing, or mountaineering.
Arc'teryx Alpha SL Jacket - The Alpha SL Jacket is the lightest and most packable of the Alpha line. This jacket provides complete weather protection without all the bulk, making it the go-to jacket for light and fast fanatics. The helmet-compatible storm hood and HemLock inserts to keep the jacket in place under a harness make the Alpha SL idea for alpine climbing.
Arc'teryx Alpha LT Jacket - Ideal for the light and fast alpine crowd, this highly technical mountain jacket also crosses over to urban environments. The Arc'teryx Alpha LT features an improved speed hood and the harness HemLock keeps the jacket hem from rising above a climbing harness.
Arc'teryx Alpha SV Jacket - The Alpha SV is designed to protect the wearer from the most severe weather conditions. This Gore-Tex Pro Shell features a drop back hem for rear coverage, helmet-compatible storm hood, and HemLock inserts to keep the jacket in place when you're wearing a harness. It's an ice climber's dream.
When you're getting serious on the mountainside, Arc'teryx Alpha pants will keep you comfortable and dry. Arc'teryx Alpha LT pants feature 3-layer Gore-Tex Pro Shell waterproof protection for alpine climbing or ski touring. Tougher still, are the Arc'teryx Alpha SV Bib Pants. Also featuring Gore-Tex Pro Shell fabric construction, and a tall Schoeller Dynamic GNS stretch-woven bib for breathable warmth and mobility.
