Appropriately named after those long often chilly breaks in the action between pitches the Arc'teryx Dually Belay Parka offers incredible warmth that's highly compressible for easy backcountry transport. Laminated to a DWR saturated shell two layers of ThermaTek™ insulation trap heat with amazing efficiency. This continuous filament hollow core fiber receives an infusion of heat activated DWR during the production process rendering it hydrophobic (water-hating) just like the laminated face. The loft is super resilient so it always bounces back to a toasty state of puffy performance. A two-way WaterTight front zip also guards against discomfort as you watch that black squall march toward your perch on some remote north ridge. Inside the Dually Belay Parka you will find two internal mesh pockets great for making sure your energy bars remains chewable.
