That's what I've run into--water too hot to keep me cool. I don't mind the Camelbak water getting a little warm, but when the water in the cages gets too warm it's only good for dousing to stay cool until I can get somewhere to get ice water. I've wondered how people do it with carrying all those bottles on their bike and staying cool and refreshed with the water.
