Every season brings its cold days, summer too. The lightweight, compressible Cerium will be your choice for nights at camp, cold early mornings, and high-altitude rest stops. Its hybrid design strategically maps fluffy 850 fill down to areas that need insulation with the air-permeable Fortius™ Air 50 softshell under the arms, on the sides and around the waist, so the garment is stretchy and temperature regulating. A padded StormHood™ hood adds warmth. The result is a versatile hoody that provides precise thermal performance, ventilation and freedom of movement.
