A packable pullover for light and lofty warmth, the Fjallraven Expedition Pack Down Anorak holds in heat when the temperatures dip or we stop for lunch or trailside selfies. Worn on its own or under a shell, this pullover features 700 fill power down to keep us warm without weighing us down-plus added synthetic insulation over the elbows and shoulders to protect against added pressure and moisture. We like to slip this over our head when we stop for a quick break on the trail, enjoy a panoramic view from a chilly summit, or settle in next to the campfire after a long day of backpacking.
