It looks like you are covered. No reason to switch to a foil loaf pan, the mess tin is much better. Bulkier and heavier, but a lot of the old style steel or heavy aluminum ones dont' squash unless they are run over by a car, and even then, it isn't a given that they are dead. On the other hand, the foil loaf "pans" always seem to spring a leak when I fold then unfold them. Nifty idea, but in my experince, not so good. Maybe I just need better ones, or it could be an elevated Murphy factor on my part.

If I understand you correctly, it sounds like you want to trim this down without loosing functionality. If I'm wrong, insomnia is to blame.

The are few things I can see to be worth loosing, starting with the salt tablets and maybe the hemostats. What do you have in mind as a role for your hemo's?

Don't bother with a full utensil set, you only need a spoon.

Swap the fold-a-cup for a cup around your water bottle.

If you think your fishing kit is overkill, trim it down.

Is your sponge vacume packed? If not, at least put into a small zipper bag and squeeze the air out of the bag and the sponge.

Coffee AND tea AND cocoa? Pick one, and move some stuff into the mess kit with the new open space.

Rather than the gatorade packets, try Emegen'C. Does't linger, tastewise, in the water bottle, and the packages are smaller. And you are getting fewer carbs, so you can use the water more efficent, and a lot of vitamins.
