2qt Collapsible Water Canteen

This is a genuine US military issue 2qt collapsible water canteen.  This canteen is made from a semi-rigid heavy-duty plastic that will hold up over time, and is soft so that the canteen can collapse when empty.  This canteen features the M-1 NBC screw-top lid that has a pass-through opening on the top, designed for use with a gas mask system where the canteen acts like a bladder.
