Gaëtan, the Evadict product manager, tells the story behind the 15 L ultra trail running bag:
We wanted a bag that'll take you to the end of your trails in complete safety and that can carry all your mandatory gear. We took our customers' opinions into account, for instance adding the smartphone pocket. We designed it for ultra trail, the most demanding category there is. Then we did two series of protocolled tests, which yielded excellent results. We're proud of this product, we spent a lot of time working on its stability, compartmentalization and accessibility.
