Used only a few times for mountain climbing. Purchased at an outdoor select shop somewhere, but I forgot the name. It's very lightweight, so it's convenient to carry. Size can be adjusted with the elastic cord at the back. Perfect for mountain climbing, trail running, and other outdoor activities. ※The item for sale has been in the hands of an individual and is used clothing/a used item.
