Say hello to the Convoy Series Coolers, a collection made for day trips, long-haul adventures, and everything in between. The heavy-duty Coleman Convoy Series 28-Quart (26.5-Litre) Portable Cooler 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.
