The Rab Evolute Hooded Jacket was built to take us up steep mountainsides. Whether it's cool and sunny or dark and stormy, this versatile midlayer ensures we stay comfortable with a breathable, moisture-wicking construction that adapts to changing conditions. PrimaLoft Evolve Active insulation is designed for moving fast in frigid weather, whether we're hiking our local trails late into the fall or skinning into the alpine on mid-winter tours.
