This item is waterproof and cold-resistant. I believe it has an ideal down-to-feather ratio of 80% down and 20% feather. The size is M, and I am about 170cm tall. It's roomy enough to wear a sweatshirt or something similar underneath. The hood is removable (button type). The outer pockets have Velcro closures, and there is one inner pocket on the left side. The cuffs can be adjusted with buttons to prevent wind from entering. Please understand that this item has been used!
