A step up from the very popular Simms Coldweather Shirt. A smooth lined interior is very comfortable and warm. Has a zipper pocket and a button pocket. A great layering piece, or for daily outerwear.
From Simms: Simms' Guide Flannel LS Shirt is a favorite of the people who spend the most time on the water: professional fishing guides. Made of warm, double-layered flannel, the men's shirt wicks moisture and provides UPF 50 sun protection. Angler-friendly details include gear-ready pockets and an easy-access tool stash near the lower hem.
