The first thing that comes to mind is lack of scissors. Even though you carry carry scissors and blade as part of your EDC, I would prefer a fully equipped, independent FAK. Remember, you might be the one who needs assistance, and then the scissors might nit be accesable.

Good quality tweezers or forceps should be there as well. As for the rest of the contents, I think it is a fair kit. It could be expanded, as you are not restricted by weight or size (as a back packer would be)

I like the ideas of the Tuppawear as a storage container!
