Yep, I had a pack all chewed up by a porcupine when I lived in Ontario. Chewed on the shoulder staps and the padded back (it was a frameless daypack).

I should have thought about the possibility because the year before in the same camp porcupines chewed all the canoe paddles at the places your hands would be. Live and learn!

I am looking forward to hearing more usage reports! I had no idea that one could get a truly custom pack made like this. Good to know!
