CamelBak Podium Big Chill 25oz Bottle
The CamelBak Podium Big Chill 25oz Bottle is double-wall constructed to keep water cold twice as long, while CamelBak's innovative Jet Valve ensures you're drinking the water, not wearing it. Plus this bottle was the first insulated bottle to be team issue at the Tour de France.
Does an excellent job of keeping your drink cold and the valve does what it says and helps keep your drink in your bottle or in your mouth. It also seems to do a better than average job of not picking up the flavors/ smells of drinks that you put in it.
This is a good bottle, doesn't drip if upside-down, and is easy to squirt while riding. -1 star because it doesn't stay cold as long as some other bottles.
