Excitement about the winter Olympics has been great for business at Burton, the Vermont-based snowboarding company. At its Westfield Montgomery Mall store, which opened last August with a broad selection of boards, boots and winter clothes, “jacket sales have been up crazy amounts” since the Olympics began, says assistant manager Cory Brown. But there’s one item in high demand that the store just can’t provide: the patchwork jackets worn by the U.S. snowboarding team. “Only the athletes can wear them right now,” Brown says. Not for long, though. A civilian version is coming later this year.
