The K17 is finally my light and minimalist bag, ideal for all my summer outdoor activities. It's great for carrying my sail because it has a dedicated compartment, independent from the rest of the bag, in which I put it directly, but not only... I love to use it for my multisport events because it adapts to all situations: trail, mountain bike, mountaineering, etc. Very comfortable, it fits well on the back, even during a fast run thanks to its wide straps and the compression system that allows to limit the volume and to press it against the back, and if needed, the belt stabilizes it even more. And then it is super practical with the multiple storage on the straps. Everything is always at hand! And for the final touches: the helmet holder and the pole holders.
