I have some Mountain House meals my Dad gave to me, and he doesn't even know how old they are. I'm guessing from when he was an avid hiker, they are 20 ish years old. It's an old design packaging and no date stamp on it. Just wondering the approx shelf life of these products.

Also, I have some more current MH meals that I broke open and ziplocked last October for a trip I did. Still have some of the ziplocked food left and thinking about taking them on my trip this weekend. G2G or no? Not sure what the shelf life is after you open it up.

I appreciate any insights!
