Shirt that never needs washing and won't smell, even after 100 days of continuous use

A New York City start-up is peddling a men's button-down wool shirt that the company says never needs washing and won't smell, even after 100 days of continuous use, including after a sweaty 5-mile run. 

Cutting-edge clothiers Wool&Prince says it has put the wool used in this 'no wash' shirt (still in the prototype phase) through a special process that makes it soft to the touch, resistant to wrinkles and odour-repellent.
