CamelBak Quick Grip with Podium Chill Bottle 20oz., $23.00
Features: Cold fluid leads to a cooler core temperature and the ability to go longer. The podium chill bottle did the job of keeping drinks cold through the 70-minute trail run the testers used. The valve is easy to use with good flow.
Cons: A little stiff and heavy as a result of the extra insulation in the bottle. Heavy and bulky for female users.
