This is a backpack for snowboarding backcountry! (Purchased for around 25,000 yen) I bought it 2-3 years ago and it's in excellent condition, having only been used once. I'm selling it because I rarely go to the snowy mountains anymore. The material is scratch-resistant, so there are almost no scratches, but there is a faint white stain on the bottom. I've included it in the last photo. I used it once for about 5 hours of climbing. It's 30L, so it can hold a lot of luggage, and the waist belt and backpack fit your body well, making it feel less burdensome even when carrying heavy loads.
