As a longtime bike traveler who has traveled several thousand kilometers through Europe, I've owned many pockets. No pocket I find more convincing than the KlickFix. While securing the rack even when the pockets of the "big" manufacturers such as Ortlieb and Vaude is a little more tricky, you can see the KLICKfix bags without any problems attached and removed, without which it will hakelig. Also spacers for different pipe diameters of racks are not needed. The attachment adjusts automatically and keeps the bags bombproof. This is handy if, like me uses several bikes. Exemplary are also the extra pockets in the lid compartment and a zippered inside pocket. Despite their relatively high price, the KLICKfix bags every penny worth after my first impression. Only the color scheme seems a bit stuffy. But that's to get over considering the merits of the bags.
