The Mountaineer is crafted out of rugged polyethylene that is virtually
indestructible, perfect for your long or short-term outdoor adventures.
Aluminum hinge and stainless steel locking clasps ensure that your
cooler stays intact and impermeable to the elements, even if it takes a
beating. The Mountaineer with it's 70 quart capacity may be the smallest
in the Extreme Cooler Series, but it more than makes up for it with it's
impressive ice preservation, ease of transport, and packout.
