I bought this for a 66 mile gravel adventure ride. Through every type of dry terrain; gravel, sand, very rough forest roads and technical descents, it was secure. The bottle tube is easy to use and having the extra liter beyond what�s in your bottle cages is great. Accessing gels in side pockets is tricky when grinding along since elastic is tight. I use it often as part of my general gravel kit when not wearing a racing jersey.
