I am selling this item because I used to go mountain climbing, but I have stopped. This is a Mammut insulated mountain parka with a hood. It's the perfect item to wear over long sleeves, and it has a lightweight and easy-to-move-in design. I purchased it for around 40,000 yen during the COVID-19 pandemic, but I have never used it. The size is XL in Asian sizing, which is about a size 11 in Japan. This item will be useful for mountain climbing and outdoor activities in the future. I would like to pass it on to someone who can use it a lot while it's still in good condition. Thank you.
