The durable 75% cotton/25% polyester fabric features a lofted interior for heat-trapping warmth and a smooth exterior surface that resists pilling. The polyester in the blend aids shrinkage control. The hem and cuffs are built with a wide and sturdy rib-knit for a custom fit with outstanding stretch and recovery. The generously-sized hood easily fits over a ball cap and is drawcord-adjustable for security in the wind. Finished with a front kangaroo pocket and custom graphics designed in-house at Filson.
