Coleman Xtreme Marine Cooler, 70 quarts review: This cooler from Coleman offers the most size for the money

The Good The Coleman Xtreme Marine Cooler offers a whopping 76.1 quarts of usable space, which is about as big you're going to get at this price. It was also a decent performer, beating out most of the other budget picks we tested.

The Bad The Coleman's sparse design includes an ineffective drain, and there's no latch for the lid.

The Bottom Line This is a good pick if you're looking for a king-size cooler that won't bust your budget, but you can find better performance and build quality if you shop around.

If you're looking for a good value on a cooler this summer, then you'll probably see a couple of reviews pointing you toward the Coleman Xtreme Marine Cooler. 

Coming in at a whopping 70 quarts, it's a popular pick that offers about as much capacity as you can hope to find for less than $50 (I got mine for $42 at Walmart). Even better -- that capacity claim turned out to be conservative, as the thing actually held 76.1 quarts in my tests.

The size alone might justify the purchase, but you'll find better performance if you shop around. Among marine coolers designed with boats in mind, the $329 Bison Gen 2 Cooler might be worth a look if you're itching for a heavy-duty, rotomolded upgrade with better options for extra features and customizations. 

Meanwhile, the $45 Igloo MaxCold is a better choice if you just want something cheap that'll keep drinks cold as long as possible.

The Coleman Xtreme Marine Cooler's drain was one of the least effective that I tested, leaving about a half-inch of standing water behind.

Available in stark white and designed to sit in the sun, Coleman's cooler is a classic, wide-bodied marine model intended to sit steady on open waters, but there's nothing stopping you from using it wherever you like. With no latching lid, the basic build isn't anything fancy, but it's at least sturdy enough to sit on, and it includes a couple of built-in cup holders for your beer, too.

At a claimed capacity of 70 quarts, the Coleman Xtreme Marine is the largest cooler I've tested to date. When I double-checked that number by filling it with water, it actually held 76.1 quarts before the lid finally wouldn't close without overflowing. You'll have a hard time finding any other cooler at this price that can come close to that kind of capacity.
