"Easy tips" - Review of CamelBak Thermal Control Kit

OK...when it's hot out and you want cold water, simply fill reservoir 1/2 full and place in freezer overnight with fill cap facing up. Top off with water before you leave and viola!, cold water all day long. In winter I add a disposable heat pack between the reservoir and insulating bag. This keeps the water luke warm, which is much easier on the mouth in cold temps.If it's really cold out, I'll rubber band a heat pack on the tube right by the bite valve so I don't have to clear the tube after every use.
