I have been testing my backpack(pic related) through various durability tests and scoring it. I have rated out of 10 for each criteria. Here is my criteria:

1)Fill with water and see how long it takes to dry out in the sun
>6/10
2)Jerk the zippers back and fourth as hard as possible
>3/10
3)Fill with sand and rocks to see what it can hold
>8/10
4)Drop heaviest knife from shoulder height to make sure canvas is tough
>7/10
5)Hold flame to backpack as long as possible to simulate backpack being close to campfire
>9/10

This brings my total score to 33/50. This means my backpack is quite average. Was curious how everyone else's backpacks scored so that I could pick a better one. Thanks.
