The better button-down? Entrepreneur racks up investors with promise of self-cleaning shirt

Mac Bishop shows off his "miracle fiber" wool shirt. He told CBS News' Michelle Miller, right, that he once wore the shirt for 100 days straight, without washing it.

(CBS News) A new shirt being touted as "the better button-down" aims to make laundry as we know it a thing of the past. The entrepreneur behind it claims it never wrinkles and can be worn over and over, without being washed.

Marketing grad Mac Bishop, 24, says his shirt not only looks good, but is soft to the touch, resistant to wrinkling and odor-free. To prove it, he wore one of the shirts for 100 days in a row without washing it.

Bishop told CBS News, "I've (run) four miles in this shirt, I've biked five miles in this shirt, I've thrown it on after a basketball game. It airs out. It's the miracle fiber."

That miracle fiber is wool -- but the kind Bishop uses is more than three times thinner than a human hair. He claims this is why his shirts are extra-resistant to moisture, making them the perfect garment for people on-the-go.

To bring his vision to life, Bishop turned to the online fundraiser Kickstarter. In just over a week, more than 1,700 supporters have helped him raise more than $250,000, nearly 10 times his original goal.

So, is Bishop out to say he is promoting a shirt that can literally can last a lifetime?

"Yeah, that's the goal," he told CBS News' Michelle Miller.

And what's in it for his supporters? A self-cleaning shirt to call their own.
