The North Face’s Summit Down Belay Parka is high-alpine insulation at its finest. Created with exposed belay pitches in mind, it is filled with highly compressible 800 fill RDS ProDown to provide an effective barrier against the creeping cold. ProDown has a TNF exclusive water-resistant treatment, which helps maintain loft even in damp conditions. A helmet-compatible hood, two-way front zip, glove-friendly zip pulls, and harness-compatible pockets tick off the climbing essentials. For additional comfort, the collar and hand pockets are lined for warmth, and stretch-knit cuffs help keep the heat in.
