They cost less than $10 at the Army "surplus" stores around here...

Think green.

Al Gore gets $20 for every one purchased.

But the ones at the surplus store dont advertise that they have "style"

... the double-wall canteens are great for keeping coffee hot ... and the stainless steel is fantastic for keeping odors/flavors in the liquid and not absorbing it into the canteen - like is what happens with the plastic ones ...

I have an aluminum one. Korean war vintage. Cork seal in the cap.

and to think they couldn't sell them at $60... Probably won't sell many at $30 either...
