At only 10 ounces, the Ultralight 850 Down Sweater from L.L. Bean is great on chilly days. My husband wears his on daily walks, hikes and trips to the store. It layers perfectly under a shell when serious cold sets in and it’s treated to repel moisture and dry faster than untreated down. Best of all, when it comes off you can pack it inside its own pocket. Thanks L.L. Bean!
