The coolers in competition were the Ozark Trail 45QT Rolling Thermocooler, The Pelican 45QW Elite Wheeled Cooler, and the Yeti Tundra Haul. I chose these coolers because they were the closest among the brands when it came to internal storage. I’m using my North facing deck as the staging area which receives direct sunlight at almost all hours of the day. I also placed  a small weather system on the deck rail to help get a sense of how hot surface temperatures are in the area. Whether you are planning your next hike or heading home for the holidays, the Ozark Trail Denton 20 L Hiking Backpack has you covered. The Ozark Trail Montpelier 45L Backpack is the perfect companion for a long weekend. This 45-liter pack is designed with ample pockets to pack all of your gear and a lightweight internal frame for weight support. Really glad I bought this pouch—it works with my pack’s waist belt, it’s practically weightless, and it’s the perfect size for phone, compass, map and a few snacks. Founded by a Triple-Crowner, our experience as thru-hikers allows us to design ultralight gear that can withstand the demands of long distance hiking without weighing you down. The Yeti has the most streamlined design of the three coolers, staying true to the original Yeti look and feel. The overall product weight of this cooler is 37lbs empty which is inline with the Pelican, but 7lbs heavier than the Ozark Trail cooler. The Tundra Haul features rubber clasps, which I really like, and hard plastic wheels. I spend a great deal of time on the water every summer boating and fishing in Northern Michigan. Ultra™ features woven UHMWPE fiber which is the lightest, strongest, most abrasion resistant ultralight backpack material in the world. So there you have it, when looking at just the ability to keep ice cold over a period of 6 days the Pelican has just slightly won, but we are talking about decimal points. I have to say that I am very impressed with the performance of the Ozark Trail 45Q cooler. This cooler is not only smaller in its overall size but also a fraction of the price of the competition.
