Akin to a portable, personal refrigerator that’s tough and versatile enough for any adventure, the Otterbox Trooper LT30 keeps ice iced for up to three days–and more is not unheard of. Formidable features of this 30qt capacity beverage leakproof beast include a food-grade liner, heavy-duty base, and bottle opener. The clever carry design means you can also sling it over your shoulder or cart it as a backpack.
