The key to making it last as long as possible is keeping it in a cooler with a good seal around the lid.
That makes a dry ice bomb
I've kept dry ice in rigid coolers and never had an issue with it exploding. Never...
Dry ice doesn't melt, but it will evaporate. The key to making it last as long as possible is keeping it in a cooler with a good seal around the lid.
where can you even get dry ice?
I definitely resonate with the two-cooler idea, but in my situation I'll be limited to the space on a kayak, so it isn't really an option for me.
Perhaps I'll do dry ice at the bottom, wrapped in newspaper, under cardboard, then a big, blue ice block, then frozen meat, then beverages at the top.
It's a four day, three night trip, and I'll need to get the dry ice the day earlier - so it needs to last 5 days in a cooler.

Oh, I'm a very experienced backpacker, so I'm bringing along my share of backpack type foods.
The cooler is for some nice-to-haves like ice cream, frozen steaks, and icy cold beverages. Also, for fish storage as I'll be fishing.
It isn't an either or thing in this situation
Ahhh gotcha. Sorry I deal with enough morons that I figured you were just another jackass who thought he could eat brats and hamburgers every night on the trail with no backup plan.
If you stuff is frozen you should be fine with a soft sided cooler and really just head to store and buy the thickest one you can find that is reasonably priced. They all really suck at the end of the day but you should get a couple days at least with dry ice which is all you really need and as you know if you stuff starts getting warm time to burn through it quickly.
