1937 (1908) Pattern Webbing Large pack. The Large Pack remained unchanged from 1908 Pattern Web Equipment and was primarily used when changing station or transferring between units. Normally, the pack was left with unit transport, and contained items necessary but not immediately needed, such as sports clothing, sleeping gear (blankets) and greatcoat rolled and attached to the outside, spare Battle Dress, etc. The "L" straps used with the haversack were also used on the large pack, attaching to the large brass tags on the upper rear of the pack, and interfacing with the blanket straps via 1-inch buckles
