UPS is revamping its uniforms for the first time in decades.
The uniforms worn by 125,000 drivers, known as "browns," are getting what the company calls the first major redesign since the early 1920s.

The company said its drivers are "often referred to as industrial athletes," and the new uniforms will be made of performance fabrics that stretch.
Drivers can wear a new polo-style shirt that wicks moisture. The most popular shirt, a "shirt-jack" worn untucked, is still available as an option for drivers.
Pants will be made with stretch twill with a “more modern fit.” Another uniform piece is a moisture-wicking baseball-style mesh hat.
And for the first time, the light brown shirt will have color blocking -- a dark brown stripe down the side.
Shirt sleeves and winter caps will have reflective stripes, and the UPS logo on the uniforms will also be reflective.
The company said it did beta testing of the new uniforms on 100 drivers in 30 locations.
The new uniforms will be phased in across the country, and UPS said it will recycle old uniform pieces.
