Cool insulated thermos with everything you need I’ve been looking for one of these for a while, I dive a lot almost all year round and even in the warmer months it’s cold in the morning.

The built in spoon seems cheesy at first, until you realize how convenient it is to only have to pack one item and not be constantly forgetting your flatware! It has kept everything that I’ve put into it nice…
