The Deltas – originally inspired by climbers, then refined to perform across a wide range of activities and conditions – are your go-to when thermal efficiency, stretch, and all-mountain versatility are required. Made with wicking fibres, the Polartec® Power Dry® fleece’s voided grid construction delivers a high warmth to weight ratio and has a smooth face that layers easily under a shell. The ScubaHood™ fits under a helmet and integrates a panel that wears as a neck gaiter or balaclava.
