The Canada Goose venture was born in Toronto in the 1950s by entrepreneur Sam Tick, who was the first to conceive of technical outerwear with a citywide twist. Over the years, Canada Goose has become a leading brand of high-end jackets and down jackets. The men's apparel collections are designed to challenge the most extreme temperatures, and the Canadian brand has developed a TEI (Therman Experience Index) thermal index to help identify the exact temperature range that each item can withstand while maintaining its insulating and thermal properties.
