This is all good stuff- thanks!

This morning, I tried to pin DH down on his preferences. I find myself leaning towards glass, due to it being both non-plastic and nuke-able. However, DH has concerns about breakage, particularly when he's in the field (see OP). Can anyone comment about durability for the Pyrex/Glasslock/Rubbermaid options? I'm considering stainless steel for field days....it's not like we have a microwave out there!

I'm definitely getting some of those Lunchskins! Hopefully, I can find them locally....
