Tom Bihn Pilot
I thought the Pilot would be my end-all, be-all personal item bag. I bought the black halcyon version with the thought that it would provide more versatility and enable me to easily pack it into my carry-on if circumstances warranted. Unfortunately, due to the flexibility of the material, the outer slip pocket on the back of the bag causes an annoying gap that puts items in it (magazines, boarding passes, etc.) in peril of falling out. Epic failure for my needs. I then ordered the ballistic nylon version (also black) thinking that the integrity of the nylon material would avoid "the gap". Not a whole lot better. I now use a Pacsafe bag that seems to be working.
