1.5L is the perfect size

I've put it through the wringer
Size Bought:

I know it is tempting to get the 6L, I labored over it. But am happy to report that everything that I would ever think I want to take with me on a long run was able to fit. Loads of snacks, spare socks, phone and inReach. Everything! I did have issues with sizing. I initially bought a M wanting a snug fit that would not move, but it was too restrictive for my movement and exchanged it for a L. It fit better, I was able to reach into pockets easier and still does not move about.
