I use a Nalgene for a container in my car kits. Each car has a bag with blankets, tools, etc. The bag has limited pockets and it annoyed me that little stuff was migrating all over. I settled on organizing in a Nalgene because of possible dual use...

In the Nalgene, I have

- Inova X1
- 2 AA Batteries
- Paracord (~12') (wrapped around bottle)
- Duct tape (inside bottle)
- Bandana
- Mini-Bic
- Cheapy Match Case w/tinder
- Cheapy Match Case w/Strike anywheres
- Mora (Clipper I think, strike that, it is #2)
- Sometype of AMK survival blanket

It is a tight fit... I was planning to squeeze in water purfication tablets at some point.
