Designed to layer but not afraid to fight the elements on its own, the Rab Tecton Pull-On Fleece is quickly becoming a staple in our adventure wardrobe. When temperatures are near zero we pair this with our favorite baselayer and waterproof shell and trust the gridded fleece fabric to retain valuable body heat. When temperatures are a little more friendly we trust this very same fabric to breathe with ease and wick sweat as our outer layer.
