I just got my WFR from these folks at Wilderness Medical Associates. We were give many books for the class but the one we were told "never go anywhere with out it being in are pockets was this one" It's a little bigger than a 3*5 card with a spiral backing. It's water proof and very sturdy. One of the girls dropped hers in the composting toilet at the beginning of the course; and it looked just at new after 10 days at the bottom of the toilet, as it did on the first.
