How do you improve on perfection? Add a hood! The lightest down layer in our long history, this instant warm-up is the ideal weight for layering or packing. The adaptable design features an athletic cut that allows this critical insulator to function expertly as a mid, outer or emergency layer. 800 fill power premium European goose down traps core heat, while the lightweight ripstop shell features a StormRepel® DWR finish to shed light precip and light snow. Stretch panels add mobility when reaching, twisting or turning. A simple, low bulk hem design eliminates hardware and trims from under harnesses and hipbelts. Note: the fit is trim and athletic, closer to body than most down pieces, designed to fit over a baselayer but allow for a wide variety of soft shells and hardshells to be worn on top. If you want to wear this piece more frequently as an outer layer we suggest you go up one size.
