The Rab Men's Rivelin Hoody is a light pullover providing fast-moving comfort for trail runners and hikers. It feels as soft and breathable as cotton, except it also wicks moisture and dries as quickly as you'd expect out of any performance top. This hoody's regular fit sits slightly on the relaxed side so you can slip it over a short-sleeve past the treeline. Rab added gridded mesh under each arm for enhanced ventilation.
