This is because all of the components of this cooler are made of plastic (most likely to keep costs low) and, unfortunately, these plastic pieces don’t have the life of higher-quality materials such as steel. They could also use a little beefing up to prolong their life. Visual Appeal – The Coleman Xtreme Marine Coolers follow a similar naming pattern, with a single number coming at the end of the product name. This number represents how many days it can keep items cool. Unlike other manufacturers, Coleman rigid coolers are insulated with Polyurethane insulation (PU). PU is a very dense and an excellent insulator filling the entire internal cavity of the cooler, leaving no air gaps and so improving its insulating efficiency. There’s nothing quite like that first cup of tea or coffee in the morning on a camping trip. So make sure you don’t miss out by adding camping mugs and kettle to your outdoor gear. Decathlon’s selection of camping mugs is made from plastic or hardwearing steel, while our camping kettles can be conveniently boiled on your camping stove. We’ve even got whistling camping kettles that will tell you when it’s ready for you to make your brew. In tandem with the Coleman Xtreme Coolers are the Coleman Xtreme Marine Coolers. The Coleman Xtreme Marine Coolers take the advanced ice retention features offered up via the Xtreme technology and apply them to coolers specially designed for Marine settings.

The major issue here is that, despite the decision to use stainless steel hinges (which is a good one), Coleman decided to screw these directly into the plastic and not provide a strap to hold the lid open. The result of this is that when you open it and apply any significant force to the lid you will slowly pull out the screws holding the strap down! This can be a huge headache and essentially ruin the cooler much faster than we would have hoped. The supposed day ranges go from 3 to 6 days. As you might expect, these numbers are higher than what Coleman states their non-Xtreme coolers are good for. We will test the accuracy of these ice numbers further below. Coleman Xtreme Cooler Features Also, you will find that all Xtreme Coolers have the Coleman Have-A-Seat Support Lid. This robust lid design allows you to put up to 250 pounds on top of it. This makes it a great makeshift seat or, in a pinch (and with proper support), it can also be used as a temporary step stool. We have also found this feature helpful when you need some extra seats around the campfire. And in our comparison test, the Coleman Xtreme out-performed the other cool boxes in terms of insulation performance.

About GO Outdoors

The Xtreme Marine line is Coleman’s updated and improved offering for those in the market for marine coolers. They come with the patented Thermozone insulation but in higher amounts than the conventional Coleman marine products. Also, upgrades to the frame itself have been implemented which results in a slimmer, more aesthetic body while also being much more rigid. There are multiple selections of shapes and sizes. The larger sizes can come with either 4 molded cup holders while the smaller ones come with 2 and all sizes come with carrying handles. Sizes available include 28, 100, 120, and 150 quarts and all products are made of plastic. Insulation Ability – However, the posted cooling numbers are a bit exaggerated. This is especially true if you plan on taking this to the beach or lake in the summer. Depending on which model you go with, you should expect around 70 to 80% of the reported numbers in real-life applications. This translates to between 40 and 110 hours, with the larger coolers almost always outperforming the smaller ones. Mobility and Durability – This is a much more like the traditional shape of cool boxes. The ability to store bottles upright is a welcome change. While we didn’t see quite the numbers that Coleman stated, they weren’t too far off. This does bring up an interesting point, however. Coleman simply states that their coolers will “keep food cold” for up to a certain period. This could be interpreted differently from how long it keeps ice, as even cold water could do a good job of keeping items cold. Because of this, we feel that their stated cooling performance is pretty accurate. And the results, particularly in the larger sizes, show that Coleman Xtreme Coolers can keep up with the ice retention values on some of the more popular premium coolers on the market. To get a better idea of real-life results, we did some of our in-house tests. Our go-to method is to fill the cooler approximately ½ full with ice and leave it outside. We will then open it every half hour or so to emulate real-life use. The results were as follows:

Other great features include a leak-resistant drain that helps you to remove melted water. This is more common on larger-sized coolers as smaller ones are much easier to tilt over yourself. The Coleman Xtreme Coolers are an upgraded version of their conventional chest coolers and are intended for those people looking for cooling power that needs to last for several days. It contains extra thermozone insulation that will reportedly keep items cool for up to 6 days. It comes in a couple of color options, has wheeled configurations, and is available in 28, 52, 62, 70, 100, and 120-quart options. All choices have attached handles for convenience and are made of plastic. Insulation Ability – Online prices vary quite a bit with these products, but almost all fall in the budget category. You will find some small fluctuations depending on which size you go with. Typically, smaller sizes will have a higher dollar per quart rate and you will also pay a small upcharge for wheeled models. Also, all Coleman Xtreme Coolers come with the Have-A-Seat feature which can handle up to 250 pounds sitting on the lid. This is particularly helpful on the Xtreme Marine Coolers as they can double as extra seats or benches while on the boat. There is a common name designation among all Xtreme Coolers that needs to be discussed. After the storage volume, Coleman has included a number ranging from 3 to 6. For instance, they offer the 62 Quart Xtreme 5, 28 Quart Xtreme 3, 120 Quart Xtreme 6, etc. This number represents how many days your items will stay cold. So for instance, the 62 Quart Xtreme 5 will supposedly keep items cool for 5 days.There are a variety of handle options depending on which model you go with. For the 28-quart model, there is an overhead comfort-grip bail. This is a very comfortable bail and does a good job of controlling this relatively small cooler. As you step up, the larger sizes all have side-mounted comfort-grip handles that can rotate almost 180 degrees. This gives you a good angle to grab the cooler. That being said, when it is full, we recommend finding a buddy to help you move it.
