This is a Columbia jacket. It came with an inner layer, but I lost it, so this is just the jacket itself. The hood is detachable. There's a pocket on the back where you can store it. It has many pockets, making it very convenient. Points of concern: There is a black streak-like stain on the inside back. Please check photo 11. There is also a stain-like mark on the inside hem. Please see photo 12. I think you can make it even warmer by pairing it with your own inner layer or down jacket. The size is XS, but I think it could also fit men who wear a size M and women who wear a size L. Size measurements: Length: 65 cm Width: 53.5 cm Sleeve length from center back (raglan sleeve): 81 cm. Sleeve length from shoulder: 71 cm. Material is 100% nylon. I have added more photos, please take a look. L.L.Bean Montbell Uniqlo GU GAP Workman
