Ten C Smock Snow Jacket in Navy. The technical Nastrato fabric is a recently developed 3-layer nylon that acts as a breathable / waterproof membrane bonded to the outer nylon fabric and inner lining. Taped seams internally ensure the jacket is waterproof whilst 4 external button down pockets enhance functionality. Initially intended to be a jacket for troops working in cold conditions, this jacket is a functional piece that is ideal for life in the outdoors. We also sell a number of interchangeable down filled and sheepskin liners that find inside the jacket and are sold separately.
