Adam Eidinger, long one of DC’s most active activists, is also a businessman. He’s had his own PR firm for several years, and now he’s firing up a hemp clothing store.

The shop will open later this month in Adams Morgan, says Eidinger, who briefly achieved international fame in 2004 by disrupting the Washington Nationals introductory news conference to protest the public funding of a stadium here.

“Every major city in America already has a hemp store,” Eidinger says. “Now DC will, too.”

Eidinger, who counts among his good fights a long-time advocacy of marijuana law reform, says he thinks hemp shoes, going from $60-$110 a pair, will be big sellers. His store’s shelves will also be stocked with hemp shirts and pants, hemp cosmetics and hemp food.

Even the shelves will be hemp.

“We built the whole store out of cannabis,” says Eidinger. “It’s all hemp fiber board.”

But — sorry, Nats-heads — the shop won’t be selling hemp curly “W” caps, Eidinger promises.
