I understand that there is another thread about hydration but I more specifically was curious if anyone employs the CamelBack Hydration Systems
http://www.camelbak.com/index.cfm, Personally I have found these great for other activities but never thought of the uses for something such as umpiring. I of course the only application for this would be for the PU but I do think it would be and suitable water source for the game. Although I could for some people see where it may be an incumberence. The back I have considered getting holds approx. 2.1 Liters, I am guessing about 4.5 lbs of extra weight. I personally do not believe it to be too much of an issue but I am just looking for some opinion as to the use or reasons not to use such an item.
I of course would be wearing this under my shirt in concert with my CP.
Thank You
Also I live in Florida so hydration seems as though it is going to be a significant issue as it has been every year!
