This is the 【Okara】Litet (リーテッ) Black backpack. It's an Okara backpack from the brand produced by Ai Nitta. I bought it about two years ago and used it as a sub-bag for travel, and then stored it at home. I haven't used it in the mountains, only used it 2-3 times in the city. I'm selling it now while it's still in good condition because I don't think I'll be using it much in the future. Color: Black Number of times used: 2-3 times Retail price: 17,600 yen I don't think there are any noticeable stains, but please check the photos. It's in good condition, but it's still a used item, so please refrain from purchasing if you are sensitive to this. Please consider purchasing only if you understand. Please note that it will be folded up small for shipping. From the HP: okara ai nitta ● Roll-top style This backpack is designed for day hikes with a capacity of approximately 12L. The roll-top design prevents rain from entering the interior and maintains a clean silhouette regardless of the size of the load. The main material uses "TORAY" waterproof and breathable 3-layer fabric, making it a genuine specification that is resistant to water. ● Side zipper Unusually for this type of small backpack, there is an opening on the side of the main body that can be opened and closed with a water-resistant zipper. Even though it is highly waterproof, you can take things in and out from the side without having to open the roll-top, which is a bit difficult to access. Furthermore, you can access the inside even while wearing it on your shoulder, so you don't have to take the backpack off every time you want to take something out.
