Lets see, off the top of my head:

1. Water filter
2. Bandage
3. Sling
4. Oven mitt
5. Dew collector
6. Edibles basket
7. Distress signal
8. Dust mask
9. Sun screen
10. Neck cooler
11. Dish rag

Lots more that I just can't bring to mind right now. When I am in the woods I always have one on me and at least one in my pack.
