Very beautiful and high-quality tankbag, there is no doubt about it. Its magnets are quite strong, so it doesn't change position while driving. However, there are also straps for anyone who thinks it is necessary, for example, in case the bag is overloaded. Also, two waterproof covers are provided, a small one and a large one, as well as back attachment straps. The only complaint I have is that in the photos, it appears much larger than it actually is, meaning it doesn't catch your eye for its 40L capacity. Recommended!
