The most durable jacket in the Beta series, this all-mountain hardshell delivers professional-grade protection against driving rain during summit climbs. Its hybrid construction combines GORE-TEX PRO ePE fabrics—reinforced shoulders for extra toughness and a lighter body for mobility—ensuring your core stays completely dry. Features include a helmet-compatible DropHood and convenient access points designed for technical use.

What's been updated: Updated with 100D and 80D GORE-TEX PRO ePE with DWR (Durable Water Repellent) free from intentionally added PFAS. Enhanced fabric lamination and updated cordlocks improve durability. Lightweight RECCO® reflector in hood brim provides safety and searchability in emergency situations. New patterning minimizes fabric waste, saving material—the equivalent of 400 jackets—in the production process.
