DA PAM 670-1 4–9. Combat uniform trousers
a. The combat uniform trousers are worn buttoned and with a belt. Soldiers will wear the trousers tucked into the top of the boots or bloused using the drawstrings at the bottom of the trousers or using commercial blousing devices if the trousers are not tucked into the boots. The legs of the trousers must be long enough to allow blousing over the combat boots. Personnel will not wrap the trouser leg around the leg tightly enough to present a pegged appearance or insert any items inside the trouser leg to create a round appearance at the bottom of the trouser leg. When bloused, the trousers will not extend below the third eyelet from the top of the boot.

b. When buttoned and waist straps are adjusted [standard ACU trousers are no longer equipped with waist straps], the trousers must fit easily at the waist. The bottom edges in the front of the coat will protrude if the coat is too snug at the waist and hips. The crotch of the trousers should not bind. Trousers must fit loosely enough at seat to allow squatting and bending.

c. Uniforms equipped with knee pouches for internal knee pad inserts must be closed at all times.

What's the difference between the ACU Trousers and the IHWCU Trousers?

The IHWCU (Improved Hot Weather Combat Uniform) is the most recent utility uniform authorized for wear by the U.S. Army that modifies both materials and construction of the ACU trousers. The most noticeable of the changes to the trousers are the quick-drying material and the gusseted knees, which allow more range of motion when moving form the standing to kneeling positions.
