So I migrated my BOB to a new edition of the same pack (maxpedition) and found out some of my food had spoiled and opened.
My powerbars were smooshed, cracked, and oozing, not one was in 'good' condition. My pack is ~3 years old and I use it when I go camping, 4wheeling and ATV'n... it rides strapped to the back of one of them. I don't use things in it regularly but I do access it occasionally. I also had some beef jerky in there that was sealed and super greasy, and I was able to break it in half it had dried out so much.
On a + side my sardines were in perfect condition
Also my mainstay was still holding up but the food in side had def. loosened up and was no longer tight in the vacuum seal.
Another thing to take note of was my trioxane tablets had almost made it through their mil. wrapper!! This could be extremely dangerous and bad if it was near your food supply as it is not healthy at all.
So, it seems anything with an aluminum/metal type wrapper has cracked, ripped at the seams or got a hole poked into it.
What are you keeping in your BOB to eat that can handle real every-weekend type carry?
If I had room I would use a nalgene bottle to hold the items that can be crushed but my pack is full!
