Say hello to the Convoy? Series Coolers, a collection made for day trips, long-haul adventures, and everything in between. The heavy-duty Convoy? Series 28-Quart Portable Cooler, White is made to move using the nonslip-grip reflective rope handles, perfect for a weekend camping trip or an all-day tailgate. Every sip should be a cold one, so we added a fully insulated lid, body, and heavy-duty latch.
