Another day in the park: endless belays as spindrift washes over in waves, hurried pitches up graupel-filled grovel fests and pulling the ropes under shimmering stars. Normal duty for our Nano Puffå¨ Hoody ranges from sleek micro-belay parka to an insulated jacket on quick alpine dashes. Its simple, elasticized hood opening adds thermostat-like warmth, and the low-bulk, hydrophobic, highly compressible PrimaLoftå¨ Gold insulation (60-g) traps heat with remarkable efficiency, even when wet. The wind-blocking, moisture-shedding 100% recycled polyester ripstop shell with a DWR (durable water repellent) finish glides effortlessly in your layering system, and a soft, wicking interior storm flap and zipper garage add chin comfort (when all hell‰۪s breaking loose, the little things help). The hoody stuffs into an internal, zippered chest pocket that has a carabiner clip-in loop. It also has two zippered handwarmer pockets, elasticized cuffs and a dual-adjust drawcord hem to seal out wind and seal in warmth.
