illing a Canadian mountain sheep is a little like climbing Everest. It’s expensive and arduous and t ypically involves terrible weather. Clothing is critical, but hunters can’t wear the garish, down-stuffed suits that climbers in the Himalayas favor. Sheep, it turns out, have incredible eyesight: Sophisticated camouflage is essential. “I’d say 80 percent of the hunters I know wear Kuiu,” says Bob House, who charges $40,000 for guided expeditions in the Yukon. “I absolutely love it when my client steps off the plane and is fully outfitted in that stuff.” If paying tens of thousands of dollars and traveling to a remote part of Canada to kill sheep doesn’t already signal how serious someone is, Kuiu does.
