The First Light Hybrid Hoody is an extremely versatile, insulating midlayer that combines the benefits of First Light insulation with key parts made from a merino wool blend. It insulates, breathes, and moves with you during early morning starts, descents with a headlamp, and everything in between. This dynamic hoodie features migration-resistant PrimaLoft Silver Insulation Active in the hood, chest, and arms, as well as a merino wool blend on the body and under the arms for enhanced breathability and freedom of movement. The lightweight Schoeller outer material over the insulation features NanoSphere technology that withstands unexpected weather conditions, and zippered chest pockets provide space for small items.
