The Baltro 65 from Gregory, known for its high-end backpacks. Although opinions may vary depending on the individual, this item is in very good condition. For information on its features and performance, the official website is easier to understand, so please refer to the URL for the Baltoro 85 Pro, which has similar backpack performance. https://www.gregory.jp/outdoor/type/backpacking/gr-142442-9574.html Perfect for winter mountain climbing with a lot of luggage, backpacking, and graduation trips. Thank you.
