I bought this for mountain climbing, but due to the pandemic, I never used it and it's been sitting around. It's been opened, but it's in near-new condition. I'm selling it to get rid of unused items during the year-end cleaning. 【Product Description】 ・This is a rucksack that can be used for outdoor activities and mountain climbing. ・Mesh material is used on the part that touches the back, so it has good breathability. ・Thick cushions are attached to the shoulder and back belt parts. ・There are many types of pockets, so you can separate items by where you put them. To prevent any problems, please read the profile section before purchasing.
