This is a backpack from UNTRACK, a high-end apparel line for everyday use developed by ace, a very popular brand of business bags. The color is navy, and it's a size S made of Ventile fabric. Size: H41 x W29 x D14cm I bought it about a year ago and used it about twice a month for everyday use, but it was a little too big for me, so I'm selling it because I bought another one. I think I used it about 20 times in total. It has a lot of pockets, so it's highly recommended for those who want to organize and use various items. It has optimal pockets for wallets, smartphones, pass cases, keys, chargers, computers, and more. Also, there is some discoloration on part of the backpack, but it's not because it was used for a long time, but rather a characteristic of the high-quality Ventile fabric. I think anyone who uses it will experience similar aging. The retail price was around 28,000 yen, and it's a high-quality backpack. Thank you. The following is quoted from the official website: ★Ventile★ Fabric woven at high density by tightly weaving fine-count cotton twins. It is quite dense and has the function of preventing water and wind from entering, despite being a natural material. What is noteworthy is that it has almost waterproof water repellency due to the high-density weaving, not processing. In UNTRACK, we have further processed the back side of this fabric to create a sense of tension and luxury without compromising the texture of the surface fabric. ※This product uses Ventile, which is made by densely weaving natural cotton.
