Made for the climb and moving at speed on mountain trails, the Delta Hybrid delivers freedom of movement, thermal comfort, and targeted wind resistance. Polartec® Power Dry® fleece’s voided grid construction creates an efficient warmth to weight ratio, and a lightweight nylon overlay resists wind and repels light moisture. The combination of materials creates a balance – warmth, airflow, protection, and the ability to perform as a midlayer or standalone – that gives this Delta outstanding versatility.
