I have the bag now for almost 2 weeks but I am already driven over 600 km of it. The attachment of the bag with the included straps works fine when you have understood once, which strap Goes Where. The bag sits very firmly and stirs even at higher speeds (170 km / h) no piece. I could stow plenty in his pocket: a pair of shoes, a pair of jeans, a pair of shorts, two T-shirts and a 1l bottle of water fits even into it. Perfect for 1-2 days on the road!
