Whats the difference between this boot and the caribou? Is it just the color and tread pattern, or are the liners different weight and the uppers different material?
PowPow- Both boots are rated to -40°. The Caribus weigh slightly more than the Pacs. The Caribu also has a deeper tread on its sole, making it slightly better for off-road hikes and icy areas. . The tread on the Pacs doesn't grip as well. The Caribus' upper is a nubuck leather while these are embossed leather. I believe nubuck leather is tougher. Here is the difference between the two liners:
