The lyngen Alpha90 Raw jacket for men is our lightest mid-layer. It is specially designed for high-intensity activities such as ski touring. It offers efficient moisture wicking and quick drying, thanks to the combination of two lightweight Polartec® fabrics with an exceptional warmth-to-weight ratio: Alpha90 direct and Polartec® PowerDry. These fabrics give it a very open, efficient structure, allowing it to be worn as a first layer. It also features a small chest pocket, integrated handguards on the cuffs and a stand-up collar for added protection.
