I have been using a small Ziplock container for my tea mug with a Reflectix cozy and the large Ziplock container for my eating vessel.
I cut a small hole in the lid of the small container for a sippy hole.
I use the large container as a shell that i put my Ziplock freezer bag in and pour boiling water over. When I'm done, I crumble the plastic bag up and put it in my garbage bag to hike out.
I also like the nesting capabilities of this kit. I keep my extra tealights, lighter, and firestarter inside the "water-resistant" setup.
Nothing new or special, but works for me.
