F-1X Side Pocket Repair?
 

I just noticed that the bottom of one side pocket of my (5? year old) F-1X has pulled completely away from the rest of the bag. (So that's how I lost that filter!) The pocket on the other side has a hole about 1.5 inches long at the bottom as well, where the strap wraps around.

Am I correct in assuming this is something that is nearly impossible to fix?

If you go to a luggage repair shop they might be able to help.
