At a feathery-nothing weight, this insulating (800-fill down), long-zip pullover with water-repellent finish provides plush insurance on those spring and fall fastpacking trips, when temps can dip and you’re chilled in sweat. Trim fitting, it is perfect for layering under a light shell or over a baselayer, and packs into its own softball-sized stuff sack. The only drawback is its lack of pockets.
