hydration

Let's say it's week 8 of a Zombie Apocalapse. The dreaded Zombocalypse!

You're doing ok. Retiring Zed's with regularity. You have a good base of operations. Plenty of ammo. Your patrol rig is old school Army web gear. The camel back hydration stytem gave out on you pretty quick, but that's OK, you have canteens.

But how do you tell which canteen has bug juice in it, which has water, and which has bourbon?

Because that is important. You don't want to hit the bourbon when you need the sugar and a steady hand. You only have 2 pouches and you are heading out into 'Indian Territory'. You don't want to choose poorly. What to do?

No worries, Blackhawk has Nalgene Canteen available for purchase. So you can SEE inside the canteen.

Sure it would be better if they were transpartent AND colorless. But if you squint you can tell the difference between the flavors. More important, you can see if there is a centipede floating in there before you drink.
