CamelBak Ultra Running Hydration Belt

I’m 5’3” 105 pounds. The XS/SM fit great around the waistline. Easy to get over my head or to step into it. Good amount of stretch. It comes with the water flask. The flask was easy to use. Easy to clean. It fills up and fits the pouch easily. There is a little key pouch with a clasp to make sure you don’t lose your key. The front zippered pouch is pretty big and it expands. It appears to be waterproof? There is also a pouch behind it. Lots of storage. Both the zippered pouch and the other pouch holds a smartphone very easily along with other items like gels, bloks, jelly beans and toilet paper or whatever. There are also little mesh pouches on the sides too. Big enough for gels or icy hot, glide. Now for the other stuff-it is wide and warm. In this cooler weather, it was kind of nice but I don’t know about the summer time. It fit fine over two layers. The water bottle fit fine. It was not sloshy. There are little bungee straps to hold it in. The first time taking it out, I fumbled a little bit but just ended up sliding it around and taking it out. ( I did not stop running while doing this) no problem. The 2nd and 3rd times, I didn’t have to slide it around. All in all, I am satisfied. Tons of storage. Light. Comfortable.
