Looking at getting an Ogio backpack from here
. I've got the hookup through my work to get them for half of the listed price.
I'm thinking either the Fugitive
or the Kirby
. Since I can get them kinda cheap, I won't mind cutting out some of the inside dividers and then will make an internal frame.
Edit: The Fugitive is 10" deep while the Kirby is only 7" ... looks like I'm going to order a Fugitive on Monday
