The U.S. Army is reminding soldiers that they've got two years to buy the new physical fitness uniform.

The service's Future Soldier Center on Monday tweeted that the mandatory possession date for the Army Physical Fitness Uniform, or APFU, is Oct. 1, 2017.

As my colleague Matt Cox has reported, the new design will replace -- and cost a few bucks less than -- the existing black and gray Improved Physical Fitness Uniform. While troops generally liked the durability of the IPFU, many wanted shorts that better concealed the groin and more female sizes.

The new PT design comes as the service is surveying troops about other uniform changes. Many respondents have said they'd also prefer to wear black PT socks -- a trend increasingly popular among professional athletes and civilians.
