My buddy and I knocked down two caribous on opening day of the season. It was my first field test of my KUIU gear. (Attack pants, Yukon gaiters, merino top, Yukon Jacket, Icon cap, and Ultra 6000 pack). All performed flawlessly. I was especially impressed with the pack - I loaded over 100 lbs of caribou on my back and hiked 3+ miles back to camp.
