The K2 summit series delivers extremely rugged and durable ice chests that deliver maximum ice retention without breaking the bank.

Our coolers are constructed by rotational molding which uses high temperature and low pressure.

This is a time intensive process but the end result is a durable, one-piece cooler with no seams for maximum durability and life, ENDURA integrated hinge system, HOLD tight anchoring points, and SURE Grip rubber feet.

We use UV stabilized polyethylene and up to 3 inches of polyurethane foam to give the cooler superior insulating capabilities and the ultimate in strength and rigidity.

    This is a well built cooler that should last a long time however the ice retention is really no better that the Coleman Xtreme cooler (which I own and this replaced). My Pelican 65 cooler outperforms this cooler by far, but I needed a cooler with the dimensions the K50 had as it fit in my boat well. I normally pack my cooler for 2-3 days with drinks. This cooler in the AZ desert heat can get 2 maybe 3 days with a towel over it to absorb some of the sun, this includes prechilling the cooler and drinks, where my Pelican can make 5 days no problem.

    I love this cooler, ice stays cold, before I go out I keep this cooler in my deep freeze, yeti is buying a brand, k2 is buying quality at a great price, for my cooler needs this one exceeds them, had an issue with Amazon shipping, k2 company pulled through, I will definitely be buying at least one more cooler in the near future. I like the green color, great size for the boat. Ps. (Make one cooler that says “unauthorized opening can result in death”) I’d buy it!

    Very happy with this cooler, we use it camping and it holds ice for 3 days. Saved money over a Yeti, but a good investment as far as I’m concerned. I bought more beer with the money I saved….

    I bought this cooler after reading a lot of reviews. SAVE YOUR MONEY and buy a different cooler! Every 2 days i’m adding 20lbs of ice as it melts fast. I have a old igloo that holds ice better than this one does! Very disappointed in this cooler and will be selling and purchasing something different.

    Great Cooler. Ice stays for extremely long time when the cooler is packed properly. Making sure you pre chill everything ice will last 5 days with no issues while camping. I can’t wait to purchase another K2 in a different size. Yeti Schmeti

    I love the cooler, holds ice well in SC summer on the lake. Hind sight I would have gotten white, surface temp on darker coolers is 50 plus degree hotter, I learned..still a study ice holding beast

    Plug leaks a little, easy fix with added o ring. if you don’t pre cool it 30lbs of ice on cold drinks will only last 2.5 days. Pre cooled and 3 bags of ice (30lbs) you can get 5 days with limited opening.

    For how much i spend the quality of this did not even come close to expectation. Half the bag of a target bag of ice melted in 3.5 hours in a car in controled climate. It was closed and everything.
