Corinne Prevot was a high school Nordic ski racer at Vermont’s Burke Mountain Academy when she tried to find a good hat for skiing. “It was so cold, and I wanted something that could handle sweat and moisture well but was also warm,” she says. When she couldn’t find that perfect hat, Prevot decided to sew one herself. Friends, teammates, coaches, and skiers from other schools started asking for her hats, and eventually Prevot was running a full-fledged business as a teenager, selling hats for $10 to $15 a pop. She named her brand Skida, the Swedish word for ski.
