Designed after the World War II Musette Bag, Milspec jumbo version displays the same classic construction with an overall larger design (15” X 15” X 5”). The military musette bag contains a large main compartment with an internal compartment than runs the full length of the bag to store a variety of essential gear. Store additional supplies in the full-length snap button back compartment and the flap closure side pocket. The adjustable backpack straps feature metal buckle clips so you can attach the straps to a separate shoulder strap to convert the musette bag into a shoulder bag (shoulder strap not included). Made with an unwashed heavyweight 22oz cotton canvas, the jumbo musette bag will withstand the weight of your gear while you travel.
