I used a Camel Back on my 3 week trip. I had it strapped to the bag behind me and had the hose tucked into my chaps to keep it handy. When crossing the south west I would remind myself to take a drink about every 20-30 minutes. It worked great.Temps were 100F+ for most of it, but I took a camelbak pack, filled with ice, and that's always done me well to keep cool on hotter days, as well as let me flip up my helmet and have a nice, cool drink of water every now and again. Today was no different.
