Kanye West,  Kendall Jenner sport Alpha MA-1 bombers. The Weeknd wore one to accept his many trophies at the Billboards in May.

When Vetements, the label currently considered fashion’s hottest commodity, wanted a partner to make bomber jackets for its new collaborative collection, it turned to Alpha Industries. Kanye West chose Alpha, too, to supply the bombers he used for his recent tour merchandise. Celebrities such as model Kendall Jenner are often spotted in Alpha’s MA-1 bombers, and R&B artist The Weeknd wore one to accept his many trophies at the Billboard Music Awards in May.

Not bad for a brand that still supplies the US Navy and Special Forces.

“When somebody asks me, ‘Who is your designer?’” says Mike Cirker, Alpha’s CEO, “our answer is the US government.”

Alpha began in 1960, as a military provider making N-3B parkas and shirts. Although it didn’t invent the MA-1, it started supplying them to the military in 1963, during the Vietnam War. Alpha’s version had a sage green nylon outer shell and a bright orange lining that, when worn reversed, made downed air crews easy to spot—a color combination still popular today.

Alpha provided those jackets until the 1980s, when the military decommissioned it and replaced it with the CWU-45/P flight jacket, which Alpha got the contract to provide. The company was then free to sell the MA-1 to anyone who wanted it, such as the militaries of Colombia and Chile.

Over the past couple years, Alpha outerwear has become a fashion staple. This year, revenue is up 30%, driven by the MA-1, which Alpha says has at least tripled in year-over-year sales. Last week, its bombers for Vetements, customized to the label’s off-kilter proportions, shared the Paris couture calendar with handmade gowns representing the peak of high fashion.
