Men's Singi Heavy Flannel Shirt

A long-sleeved outdoors shirt with a button-down collar and a regular fit, cut from soft, heavy organic cotton flannel. G-1000 reinforcements on the inside of the collar, the sleeve cuffs and the pocket flaps take the wear where a flannel usually gives out first. Two chest pockets have pen holders, and the sleeves roll up and button in place when the day warms.
