I'm 5'8 and 159 pounds and the Large fits just a bit loose, enough room to wear a sweater underneath the jacket. The bulk of the jacket is in the very strong canvas material, the lining is not much mote than flannel shirt thick. Good solid YKK style metal zipper and the lining in the arms is smooth so long sleeve shirts or sweaters don't bunch up. By itself I would consider this a 3 season jacket but wearing with a thermal base layer and maybe a hoodie it should be nice and warm as the canvas feels wind proof. The hood is nice and big, feels like a watch cap will be wearable but I'm not sure it will fit over a hard hat.
