"Freeze ups are the worst" - Review of CamelBak Thermal Control Kit

I bought this after my original tube froze up on a couple of winter camp outs. It was such a pain to get the ice out of the tube. I haven't had a freeze up since I bought it. A little tip. For overnight, tuck the mouthpiece down in the bladder sleeve and zip it tight. This further reduces freeze ups. Also in answer to the other reviews, if you open the cap and feed the cap and mouthpiece separately you can get this through most anything you need to.
