The integrated reflectors offer safety in the dark. The sturdy base plate provides more stability and protection against moisture. The rain cover supplied, which covers the entire backpack, protects against moisture and dirt. The back section is ergonomically shaped and padded with breathable mesh material. The accessories are also equipped with the best materials. The pencil cases, for example, are fully equipped with Lyra brand pens. There is a real highlight on the lid: plastic applications you can touch. This is a 3-D school companion for everyone who wants more.
