The Delta Hybrid is made to move. Worn as a high-output midlayer or standalone, it delivers freedom of movement, thermal comfort, and targeted wind resistance. The Polartec Power Dry fleece has a voided grid construction for an efficient warmth to weight ratio and a smooth face that layers easily under a shell. A lightweight nylon overlay resists wind and repels light moisture. The combination of materials creates a balance – warmth, airflow, protection – that gives this Delta its outstanding versatility.
