Double-wall ChillJacket construction keeps water cool for hours with its airtight, foam-lined insulation. Soft and easy to squeeze for effortless water flow.
Great bottle....I own several now. They keep water cold even on long summer rides...much better than other insulated bottles. Durable and the jet valve is silk. To top it off...got it on sale for under $10. Score!
It works fine on the hot tropic, so it mostly like work on any place. Recommend it.
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.
