Filson runs large. I wear medium in everything and needed a small in this jacket. Plenty of room for layers and you can purchase an insert as it has the zip lining as shown in photos. Loved the jacket but too redundant in my wardrobe. Weather-ready hooded raincoat with snap-front closure. Large flap pockets for secure storage. Adjustable cuffs and protective hood. Clean, rugged silhouette for outdoor use. Smoke free home. Waxed cotton shell Color: Root (an army green/brown-ish) Drawstring hood with brim for added protection Zip front with snap-closure storm flap Adjustable snap cuffs Dual-entry hand pockets Closure: Zipper Fabric: 100% waxed cotton (body), 100% nylon (trim) Lining: 100% cotton Care: Wipe or brush clean
