Comfortable but not practical
"Super comfortable but not at all practical. The water bottles (350) that come with it aren’t compatible at all. They slide to the bottom of the pocket and become inaccessible while running. The other two pockets are really big, but the opening is so small that it’s hard to reach what’s at the bottom. The back pocket is big enough for an extra jacket but not at all compatible with a water bladder. There’s nothing to hold it in place except a small loop of string. I tested it with a 1-liter bladder. It was a nightmare. The bladder bounces up and down. No support at all. Very disappointed. Handy for carrying a change of clothes or extra layers, but unsuitable for hydration."
