Bought the Raider 20-liter here from Helikon-Tex. Delivery was fast, the backpack is original. Already had a chance to test it out in the rain while fetching water around town with a friend. The rain cover worked excellently: everything inside stayed dry. The straps get a bit wet since they’re on the outside, but that’s normal. The back is very comfortable, fit me perfectly. Loaded it up pretty well, but the chest strap and waist belt really help—the backpack fits snugly and the straps don’t slip. The hardware is great too: all high quality, feels good to the touch, and works smoothly. The “beaver tail” is a real find. I throw my hoodie or jacket there so I can sit on the ground and keep the main compartment free. Turns out you can fit way more in there than you’d expect. The side pockets for bottles are good, the elastic holds them tight. A small thing: when unpacking, there was a tiny spot on one pocket, but it came off easily with a wet wipe, so now it’s perfect. A typical backpack, 100% satisfied.
