The Fjällräven Men’s Singi Heavy Flannel Shirt is a durable, warm flannel built for cool-weather hiking, camp days and everyday outdoor wear. Soft cotton flannel provides comfortable warmth, while G-1000 reinforcements inside the collar, cuffs and pocket flaps add durability in high-wear areas.

A regular fit makes it easy to wear on its own or layer over a base layer as temperatures drop. Two chest pockets with pen holders keep small essentials close, and the sleeves can be rolled up and secured with buttons when the day warms up.
