ADJUSTABLE CAMO CANTEEN HOLDER
Keep your powder dry and your canteen cold. Can’t help you with that powder thing, but this insulated camo canteen holder folds together and holds via hood-and-loop strips. Has a 5/8” ID grommet and a big hook-and-loop patch on the back to secure it. Measures approx 3-1/2" x 2-1/2" x 5" inside with room for adjusting.
