KYSEK is a team of outdoorsmen and women who have spent years in the field and around campfires with fellow hunters and anglers, noticing how every extreme cooler on the market falls short. We wanted the Ferrari of ice boxes, so we enlisted an industrial engineer. When he finally stepped away from AutoCAD, we knew we had designed the superior ice chest we were looking for but never found. But even that wasn't enough, so we built our own factory to ensure unrivaled quality and optimum spec design for our highly-engineered Extreme Cold line of coolers. KYSEK coolers come packed with premium features and superior build quality, meaning they'll hold ice longer, they'll stay in service longer, and, best of all, they'll cost you less than the competition's. At KYSEK, we thought of everything, and include it on every cooler. Other coolers make you pay extra for a bulky wheel kit just to move it. Hence, they all move when you don't want them to. We employed principles of industrial thermodynamics to ensure proper placement of optimal density insulation. You'll have ice longer than your buddies. Our high-density, multipurpose lid opens to the perfect angle for its exact weight, meaning it'll stay open. We even figured out a way to check the lifespan of your ice from any mobile device. Other coolers are tough, but our KYSEK coolers are warrantied no matter what. They don't just cover manufacturer defects, they cover it all. We designed everything to be beefier, more durable, and built to last. When we say everything, we mean everything-- down to the screws. Most coolers use wood screws. We use ferruled inset nuts and machine screws to fasten hardware for the long haul. When you can get the toughest, most feature-rich, well-designed roto-molded cooler on the market for less, why wouldn't you?
