The Gregory brand of backpacks generated a sales increase of 17.2 percent to $51.8 million in 2017, according to its parent company, Samsonite International. Gregory's sales grew strongly in North America, Europe and Asia. As before, Gregory outperformed Samsonite's more lifestyle-oriented brand of backpacks, High Sierra, whose sales declined by 10.3 percent to $73.8 million for the year, due to decreases in North America and Europe. In terms of local currencies, Gregory went up by 18.6 percent and High Sierra went down by 10.6 percent.

High Sierra was the only brand within the Samsonite group that recorded lower sales last year. The group's total sales rose by 24.2 percent to $3,491 million, with an increase of 23.3 percent in constant currencies. Its adjusted Ebitda grew by 19.5 percent to $580.3 million and its net income rose by 1.0 percent to $260.6 million.

The strong sales increase was due primarily to the acquisition of two new big properties, Tumi and eBags, respectively in 2016 and last May. Excluding them, the total sales of the world's largest travel luggage company went up by 6.3 percent.
