I have no idea about the size, sorry. This is first I've seen of it and wanted to say thanks for the heads up! I've been thinking about their 32 oz bottle/cup combo but this this looks like it would suit my needs better.

I'm liking these features of this cook set:
-two 10-oz. insulated plastic cups
-stainless-steel single-wall cooking pot cooks over camp stove
-vented lid lets steam escape while cooking
-two-position handle extends for cooking. Locks in place

Thanks again, Haertig!
