UOG TOP PICK: Light, breathable, and movement-focused, the Rab Ascendor Light Hoody delivers agile comfort—a top pick for fast, technical days.
Rab says:
Adaptable, slim-fitting midlayer for when stretch and free movement are the highest priority. Built with lightweight, wicking Thermic™ S fleece and an under-helmet hood, it's perfect for moving fast and vertical year-round.
Our Verdict
A slim, breathable midlayer designed for high output and agile mountain use.
At 287g (UK12), the Ascendor Light Hoody balances warmth and ventilation with a lightweight Thermic S fleece and strategic stretch panels. The slim fit trails neatly under a shell and over a base layer. The full-front zip provides good ventilation when you need to dump some heat, and the under-helmet hood tucks cleanly beneath a climbing helmet.
Movement feels natural; the fabric stretches to accommodate reach and twisting. Seams are flatlocked and bound. As a light, movement-focused hoody, the Ascendor Light remains a strong option for active mountain users seeking a breathable, adaptable midlayer.
