The Approach Down Vest easily layers over a hoody on brisk multi-pitch rock routes or under a shell on ice climbs and alpine missions. The vest’s ultralight nylon ripstop shell features Green Theme Technology’s Empel revolutionary Breathable Water Protection Technology—an environmentally friendly, PFC-free DWR that’s superior in performance and substantially more durable than other DWR solutions. Inside, premium 800-fill, RDS-certified HyperDRY goose down insulation offers high-lofting, incredibly packable warmth that resists inclement weather.
