Oh wow! I had read in a gazillion places that you shouldn't freeze the Camelbak resevoir! But now I see that there is success in doing so!

I normally always freeze my bottles, but with the Camelback I've been resorting to refridgeration, lots of ice cubes and a mylar wrap before I stick it in its pack.

So freezing is a go, huh? Nobody has ever had any problems with seams coming apart or anything?
