Great simple durable design
Really pleased with this. I love the simple design - no valves or tubes to try and keep clean or to go wrong. A replaceable o-ring seal on the cap indicates it should last a long long time. No it won't keep your drink cool - it would be called a flask if it was - but if it's used for little adventures the extra capacity for its size is better to have in my view over the luxury of temperature. The sort of product that becomes more of a staple of your everyday kit.
