New Zealand skier Adam Hall won both days racing in the Standing Slalom competition at the International Paralympic Committee's Noram Cup in Colorado.
The defending Paralympic gold medallist in the class, Hall clocked 1min 26.67s on the first day and 1:19.46 on the second day at Copper Mountain.
"It always feels great to get the race season under way," Otago racer Hall said.
"I was feeling pretty confident heading into these races."
Hall has spent three months working in New Zealand with his new coach, Scott Olson, on and off the snow.
"We have made some positive changes which we are paying dividends on a daily basis. It is pretty exciting," said Hall.
"Leaving Copper on top is a great start and one we will keep building on for the rest of the race season."
In the men's giant slalom, New Zealand's Corey Peters took eighth and 10th placings in a field of 20 in just his second competition.
