I to have a camelback, I used it for about a year. The extra weight on my back gets on my nerves when I get in the mood to really thrash through some trails or the urban jungle. I’ve found the small packs the fit under the saddle seem to work for me. Them seem to hide the weight so I don’t really notice it as much. It’s amazing how much you can fit in them. Note the pump gets attached to the extra bottle holder mounts. 😀
