This item was purchased at a Uniqlo store about a year and a half ago. I wore it when I went skiing, etc., but I didn't have many opportunities to wear it otherwise, so it's been stored away. It's very warm, even in cold places. It's Uniqlo's Heattech Extra Warm, which is the highest-grade model in the Heattech line. It has some dust from long-term storage, but I will remove as much as possible with a lint roller before shipping! I hope we can have a pleasant transaction.
