Physical training uniform shortages through summer Published April 4, 2014 Washington(AFNS) -- Airmen trying to keep chilly temperatures from affecting their workout may have a difficult time finding the Air Force improved physical training uniform, or IPTU, pants and jackets this spring and summer. The new issued IPTU is made with a softer fabric and will replace the legacy physical training uniform, which was made of a material that created a swishing sound during movement. There will be a transition period as the legacy stock is depleted and the new stock is ordered. The shorts have already transitioned and the T-shirt is not affected. "We are in the process of transitioning sources for the pants and jacket," said Chief Master Sgt. Kecia Uyeno, the Air Force uniform programs and policies chief. "We expect a full stock of the IPTU pants and jackets back in Army and Air Force Exchange Service stores no later than Oct. 1." During the transition period, the chief encourages Airmen to rely on additional physical training uniform combinations outlined in Air Force Instruction 36-2903, "Dress and Personal Appearance of Air Force Personnel." "There is a host of long-sleeve and form-fitting sportswear undergarment options available and perfectly within Air Force regulations to augment the uniform for inclement weather," Uyeno said. "Additionally, the legacy and PT gear jacket and pants also remain available."
