Olive drab wool field trousers developed in 1942-43 were similar in design to the wool serge trousers that had previously issued except for a higher rise and wider seat to address complaints from the field for more room and comfort, especially when worn over "long john" underwear. Adjustment tabs were provided at the waist and cuffs. Wool trousers were issued in 1944 in a darker shade of OD to match the Jacket, Field, Wool, OD (Ike Jacket).
