Arc'teryx Beta SL

The Arc'teryx Beta SL is the lightest Beta, a packable hard-shell jacket designed for alpine travel and changing mountain conditions. Built around a next-generation Gore-Tex ePE membrane, it delivers complete waterproof and windproof protection in a low-bulk package that is PFC-free and highly durable. The C-Knit backer adds next-to-skin comfort and breathability, making it easy to wear during sustained movement.

On the mountain, the Beta SL handles everything from cold, windy ridges to sudden snow showers. The helmet-compatible StormHood shields your head without sacrificing peripheral vision, while pit zippers offer quick ventilation when intensity rises. A Recco reflector provides additional safety in search and rescue situations.

Designed for versatility and fast-and-light outings, this jacket packs down easily into a backpack, ready to deploy whenever the weather closes in. The measurements below support a confident fit evaluation.
