Few things ruin a perfectly good summer day than running out of water. Whether it’s for yourself to cool down, for your pup on a playdate, or for your overheated engine, having water on hand is vital – and often a bit cumbersome. Dometic GO’s 11L Water Jug fixes many of the issues that come with storing water on the go. For one, its volume-increasing design means one can eke out an extra liter versus leading competitors who can only carry a measly 10 liters. Size matters on a hot summer day, I have to say. It’s also got comfortable webbed handles and built-in tie-down guides for easy carrying and transport. But, the best thing of all is the universal Nalgene top, making it a breeze to hook in your accessories, like a filter, for even more use. Get it for $70.
