The Root Wool Pile Jacket can be worn as it is, or as a booster layer under a shell garment on extra cold days. This pile jacket is made of two soft, silent Italian fabrics. The main material is made of recycled wool and polyester, and has techno-stretch sections on the under-sleeve and in the sides. The jacket has double radio pockets and side pockets with zippers. Two-way YKK zipper at the front. This kind of wool fleece jacket goes by many names, including fiber pile jacket, but we simply call it a nice, warm pile jacket.
