Attempting to create a more standardised uniform across much of the British military, it was composed of a fairly streamlined short jacket of wool serge that buttoned to the outside of high-waisted wool serge trousers. The jacket (or blouse) was copied by the U.S. Army and was christened the Ike jacket. The sleeves of the British blouse had a forward curve built into them so that they were more comfortable to wear prone, shouldering a rifle, or seated holding a steering wheel for instance, although they tended to show multiple wrinkles near the inside of the elbow when the soldier's arms were held straight at the sides. On the trousers, there was a large map pocket on the front near the left knee and a special pocket for a field dressing near the right front pocket (on the upper hip).
