The Alpha Lochi Jacket is designed for active use in cold environments, and is reversible for low-profile use in urban settings. Polartec® Alpha® Insulation transfers moisture away from the body to keep you dry and warm, while the DWR-treated nylon ripstop shell protects you from wind and rain. Light, highly compressible, breathable, and fast drying, the Alpha Lochi Jacket delivers excellent performance in harsh conditions.
