I bought the Raider 20L backpack by Helikon-Tex in this store. The shipment arrived quickly, and the product turned out to be original. I have already had the opportunity to test it during a rainy walk—we were collecting water with a friend in the city. The rain cover worked great, because the contents of the backpack stayed dry. The straps soaked a little, but that's normal since they're on the outside. The back part is very comfortable and fits great against the back. I filled it up a lot, but the chest and hip straps significantly improve comfort—the backpack fits perfectly, and the straps don’t move. The accessories are also top-notch: the material is solid, pleasant to the touch, everything works as it should. The “beaver tail” solution is great—I can store a jacket or sweatshirt there and have the main compartment free. In reality, the backpack holds more than it seems. The side pockets for bottles also work well, the elastic bands keep them stable. The only complaint is a small spot on the pocket when unpacking, which I easily removed with a wet wipe—now it's flawless. The backpack meets expectations, I am completely satisfied with the purchase.
