I used it about twice and then didn't use it anymore, so I think it's hardly been used. * A rain cover is stored in the bottom. * The 1- or 2-compartment configuration can be switched using the drawcord inside. * A stiffening board is inserted in the back. * The color is not often seen on others. These are the main points, but if you have any other questions, I will answer them as best I can. Thank you. 【Additional Information】 The size is not indicated on the backpack, so I believe it is a size S based on measurements. The following is a transcription from another sales site, assuming this: "Lanks 28," a new standard entry model that is active in day hiking and light trekking. While small and lightweight, the main room has a 2-compartment structure with a drawstring-type divider inside. This makes it easy to pack and take out your luggage. In addition, a PE plate with an aluminum bar is placed on the back. It can be shaped to match the curve of the back, improving stability and fit. Of course, a rain cover is built into the bottom of the bag. It is also easily accessible and can handle sudden changes in weather. 【Size】Width: approx. 33cm, Height: approx. 61cm, Depth: approx. 26cm 【Back Length】approx. 41cm 【Capacity】28L 【Weight】1100g 【Material】KS-N210R/S DM 【Specifications】PE plate with aluminum bar, built-in rain cover, air cool mesh back, front pocket, hip belt pocket, chest strap, 2 compartments
