Well, where to begin?
Plastic is pourous! Plastic can, and will, take on the smell/flavor of whatever is stored in it. So, if you smoke many blends it can take a few containers as zero's with/all ghost the container.
Light is evil (to pipe tobacco) so the darker the container, the better.
Sunshine makes stuff hot! So you not only need a variety of dark containers, you need to put them in something that will keep them in the dark, and cool.
Finally, tossing in a humidity control pack is always a good idea.
That being said, I camp a lot and just bought a fabric insulated lunch box and keep a few garage sale Tupperware sandwich containers in it.
