The Beta SL Jacket from Arcteryx is the lightest in the Beta series, purpose-built for the demands of alpine and mountain environments. Engineered for maximum versatility, it delivers complete waterproof, windproof, and breathable protection while maintaining exceptional lightweight packability, perfect for climbers, hikers, and backcountry adventurers. At its core is the innovative Gore-Tex ePE membrane, a next-generation material that is light, strong, durable, and PFC-free, offering reliable weather protection without harmful chemicals. The C-Knit backer technology enhances comfort against the skin and improves overall breathability, making it ideal for high-output activities.
Designed with functional details, the Beta SL features a helmet-compatible StormHood that shields you from the elements without obstructing vision, pit zippers for rapid ventilation during intense activity, and a built-in Recco reflector that can assist in emergency search and rescue situations. In keeping with a commitment to sustainability, this jacket is free from intentionally added PFAS. The advanced ePE membrane technology is lighter and thinner than previous generations while maintaining the same strength and durability.
