You can’t get much tougher, or cooler, than a Yeti Hopper M30, the first totally leakproof portable ice box. It’s so well insulated that ice lasts for days, while it’s a cinch to carry and ideal for those on the move. Whether spending a weekend at a campsite, a ranch or a day at the beach, you can be sure that no matter what the atmosphere outside, your drinks will remain very, very chilled.
