Coleman has been designing and manufacturing coolers for over 50 years. Coleman coolers come in all shapes and sizes but there are four main categories to think about. Chest Coolers, Jugs, Personal Coolers and Xtreme Coolers. The Xtreme range of coolers is the top of the Coleman range. Guaranteed to keep ice for 5 Days at 32 degrees, these coolers are extra rugged and super insulated so perfect for a longer camping trip. The Chest and personal coolers are guaranteed for 4 days ice at 32 degrees. So they are still great coolers you just need to choose which size suits you and if you want wheels or not.
