this is the older model,which I brought to take fishing its almost un breakable being made from stainless steal and has a lid so if you knock it over you wont loose your drink,being like a vacume flask it keeps hot things hot (up to 6 hours) and cold things cold(up to 24 hours)but for me the main thing about this product is the size it holds about a pint! and is so robust you can just throw it anywhere in your kit and its strong enough not to be damaged.its about as rugged as a fire place
buy one and you can be buried with it and when they dig you up centuries from now they will dust it off and use it.I cant give enough stars, and that is the old version the latest model must be the dogs
gonads!
