The classic army canteen style is now molle compatible in the stylish ACU/UCP digital grey green camo that is now world renown as the US Army Camo Pattern. The Canteen pouch and Canteen are made in the US for the Army to keep the soldiers hydrated in some of the toughest environments on the planet. The Bottles are BPA free and were BPA free before it became a thing. When it's this good quality you don't need to ask any questions Most Canteens come equipped with a Gas mask hydration link port. What's that? remember I said "toughest environments on the planet." Now add an enemy who wants to use chemical attacks on you? You can drink through the canteen cap with the new gas masks straw that links to the canteen. Yes these are good for Camping too;)
