CamelBak UnBottle Hydration -Review
PROS: In order of hydratation on a cycle touring the Camelback was for me my best buy. More than enough 3 litre volumen, keeps the temperature of the liquid (wáter in my case) inside quite a long time. On the trike it fitted like a glove behind the hair, easily reachable, and easy access to drink it.
CONS: None
