Filson Insulated Flannel Shirt

The Insulated Flannel Shirt is patterned after the tough outdoor shirts of the 1970s. Its 6-oz. cotton flannel is woven in a durable basketweave that holds up to years of wear. Inside, quilted insulation made from 100% recycled polyester traps heat, dries quickly, and keeps weight down.

The front secures with sturdy buttons, with adjustable cuffs for fit. Garment-washed for shrinkage control and comfort from the first day.
