CamelBak Podium ChillJacket 21oz Bottle
CamelBak's Podium ChillJacket Bottle is the first insulated bike bottle that delivers the performance you want and the insulation you need, without compromises. Double-wall ChillJacket construction keeps water cool for hours with its airtight, foam-lined insulation. Soft and easy to squeeze for effortless water flow.
This is an excellent water bottle with a great design. The jet valve prevents accidental spillage and the bottle is very easy to squeeze or suck water from. The one downside is that dirt tends to collect inside the mouth-piece during muddy rides.
