The future of baggies

I've seen cloth snack and sandwich bags for a couple years now, but haven't made the dive into using them. Until I saw this helpful review at Kitchen Stewardship. I really like the thought of the Wrap-n-Mat.

We use cloth placemats and napkins already when picnicking because they don't blow away like their paper equivalents. We don't have much plastic baggage on such occasions. I'll have re-usable containers. But I usually just clear out the pantry and fridge, and pack an entire loaf of bread, and entire jar of jelly, etc. Everyone makes their own sandwich(es) on site. I'll have one sandwich-sized plastic bag with a wet washcloth for cleanup and storing sticky knives and spoons.

But I'm thinking about school lunches. I now have two high school kids making lunches every day. How do you get a high school kid to use a wrap-n-mat? Discussions will be following.
