I was able to get two containers from walmart that fit right into each
other. Along with the zip lock bags the contents stayed perfectly dry. I
think the trick is to have some type of vapor barrier. My box weathered
about 3' of snow and a lot of serious rain in the 8 months it's been out
there. Ammo boxes are good too. I always use one to store my valuables on
canoe trips.
