Built for hardcore alpinists who need a midlayer that can keep up with their sweat levels and layer shuffling, the Rab Evolute Hoodie is your secret weapon against the dreaded “wet-out.” When you’re pushing hard on the mountain, it works overtime at the heart of your layering system – wicking sweat, trapping heat, and breathing like a champ – so you can focus on the climb instead of your climbing clothes.
