OK Folks...an exercise...

I like Nalgene bottle kits. Perhaps it is because the water container issue is solved immediately. Several pre-packaged kits are now on the market.

As you might imagine, most of the available bottle kits seem lacking. For instance...a survival light is not a cyalume stick. Sure, they're useful. But I'd rather have a Photon Freedom...or even a Fauxton instead!

Container...in order to use the container for liquid, you must remove the contents and find a way to carry them. Small nylon lunch bags don't take up much space...even a ziploc.

So...let's play... how would you stock YOUR Nalgene bottle kit. You have a liter/quart of space to play with. Obviously anything in a PSK would fit. But here you have more space...
