What Our Gearhead(R) Experts Are Saying:"I like this hoodie for high-output days where I'm constantly transitioning between climbing and moving. The grid fleece breathes exceptionally well and dries fast, while the slim fit layers easily under a shell. It stays comfortable under a harness and never feels bulky or restrictive."When the pace is high and the terrain is steep, we count on the Ascendor Hoodie to regulate temperature and keep us moving efficiently. Built by Rab for technical mountain days, this slim-fitting midlayer shines when we're swinging tools, booting up couloirs, or linking pitches in cold conditions where breathability matters as much as warmth. The Thermic(TM) G grid fleece balances insulation and airflow, wicking moisture and drying quickly as output changes throughout the day. Stretchy construction supports unrestricted movement, while Matrix(TM) softshell panels add durability where it counts. An under-helmet hood seals in warmth when the wind picks up, and harness-compatible pockets keep essentials close at hand. Comfortable, adaptive, and purpose-built for climbing, this is a layer we rely on for demanding ascents in cold alpine environments.
