John, an avid outdoorsman, was unhappy with every ice chest he had purchased over the last 30 years. Even the new, high-end rotomolded coolers, which possessed great individual features, failed to put everything he wanted together in a single product. John set out on a journey to create The Ultimate Ice ChestTM - one that would hold ice longer, provide both toughness and functionality, and combine all of the great attributes of the best coolers into one. Never a gentleman to shy away from a challenge, John took things a step further setting out to actually improve on these features while adding even more. Thus, Extreme Cold, LLC was formed.

John and his team set out to engineer the perfect ice chest. They studied the competition, destroyed lids, busted hinges and spent several years developing numerous prototypes to finally reach their goal: The Extreme Cold Series Ultimate Ice Chest.

This original ice chest was amazing and when people saw, touched and used it, they realized the significant leap this cooler made over its competitors. However, it was still not up to John's high standards and he went on to create an even better ice chest that most people agree is the "Italian Sports Car (you know the one) of Ice Chests." It's loaded with all the features you want and more: Dual drain plugs, lock down edges that double as bottle openers, ZeroSkidTM non-slip feet, DuroColdTM Construction and heavy duty inset wheels to help you steer clear of those pesky hernias or slipped discs.

John renamed the product KYSEK the Ultimate Ice ChestTM and created our White Wolf logo, which represents our ruggedness, wild nature, top-of-the-food-chain mentality and pack-like approach to solving your cooling challenges.

But we didn’t stop at the industry’s best ice chest. Today, KYSEK offers a full line of products such as The Rover Soft Bag Ice Chest and Trekker Backpack Ice Chest. The Rover is the perfect size, big enough to fit your contents, but light enough so that most anyone can carry it. The Trekker Backpack Ice Chest is leak-proof, insanely durable and pretty much in a class by itself compared to other backpack coolers. Our ChilSleeve roto-molded tube is an innovative way to keep six of your favorite beverages cool while you’re on the go. Our KYSEK Dry Bags are a fisherman’s favorite—from our pouch to our huge 70L, the bags keep your gear moisture-free when you’re out on the water. In 2018, we introduced the KYSEK K12 Kayak, the most versatile hunting and fishing kayak on the market with the most stable and comfortable experience possible on the water. We continue to innovate and offer more products that provide Real Outdoor Solutions to enhance your adventures.
