One last thought MP. I don't put my freeze dried in my vault. I just put it in a black stuff sack. I have never had anything bother my freeze dried food when it was by itself and stashed on the ground outside the camp area. Totally odor free. Not mice or chipmunks or bears or birds.

It was interesting to note the night we were clipped on Sawbill I had my freeze dried in with my regular food. The bear wouldn't eat any of the freeze dried. A single tooth puncture hole in each package was all I found. All the oats, granola and candy bars however were gone. Not so much as a flake left.

So my strategy is all the oats and bars go in the vault where there is at least some protection if a bear stumbles on it. I don't worry so much about the freeze dried and keep it separate especially since the packaging is absolutely air and odor tight. Unlikely the bear will find it (no odors), further unlikely he will identify it as food and then if he decides to try it will probably not eat it (based on previous encounter).......I didn't think it was that bad ;).

If your an oats man like me nothing works better than the nalgene canteen. The 96 oz fits  right inside the vault and it is easy to manipulate the bag to pour the food out. I know I have already suggested it but sometimes folk need to hear something more than once. Absolutely airtight/odor tight and extremely durable.
