Physical training uniform

A physical training uniform is a military uniform used during exercise, calisthenics, drills, and in some cases, very casual periods of time (off-duty time during Initial Entry Training in the U.S. Army, for example). The United States Army, Marine Corps, Navy, Air Force, and Coast Guard require use of a physical training (PT) uniform during unit exercise (including formation runs, calisthenics, and conditioning exercises). Some military units produce unique T-shirts with their unit insignia and motto, and for special events, this shirt is part of the uniform. Occasionally, exercise will be conducted in that branch's utility uniforms, normally with the blouse removed and the undershirt exposed (also known as "boots and utes").

From 2014 to 2017, the U.S. Army will use the recently introduced Army Physical Fitness Uniform (APFU), and the Army Improved Physical Fitness Uniform (IPFU) first released in 2000. The Army is currently allowing temporary use of the two physical fitness uniforms: the APFU and the alternate IPFU, until it is mandatory for all US Army soldiers to wear and have purchased the APFU by September 30, 2017. The APFU is also sold at Army Military Clothing Stores and costs slightly less than the IPFU. The two uniforms are similar in appearance and features, with the exception of shirt and jacket color. However, the APFU is made from different fabrics, has a pant liner and a brief-style trunk liner, and includes unisex or female sizes for the jacket and pants. The APFU was released on October 1, 2014 and the uniform's mandatory possession date will be on the same day in 2017.

The APFU consists of:

The alternate IPFU consists of:

The retirement date for the IPFU is September 30, 2017. Afterward, the uniform will be phased out and replaced by the APFU. For the time being, optional compression shorts (called "spankies" by soldiers) may be worn under the IPFU trunks provided they are black or do not extend past the trunks.

For unit runs, esprit de corps or special occasions, Commanders may have soldiers wear unique T-shirts with the distinctive unit insignia and unit colors.
