For those after a compact solution for keeping bottles cold in the outdoors, the Otterbox Trooper LT30 cooler is a great option. The LT30 features 28-litre capacity and highend thermal insulation (and food-grade liner) that allows Otterbox to claim it will keep ice for more than three days. The LT30 has shoulder and backpack straps for carrying, while the wide opening allows for easy access to that next coldie. There’s an inbuilt bottle opener, too. You can add accessories to it, and there are two zipped compartments for phones or other gear. The heavy-duty base is up for punishment and the whole thing folds down very small when not in use. The outer is tough TPU nylon, and it also includes tie-down points.
