This one is dedicated to my ALICE pack. I purchased a used basic old school ALICE pack last year and took it out for a spin. It wasn't nearly as comfy as my larger REI pack but was the perfect size. Reading up on it it souded like most people disliked this pack and deemed it uncomfortable, but I didn't find it too bad to be honest. Anyway, I decided to modify it looking at various forums out there; here are some pictures a before and after kind of thing.
I definitely recommend getting this in pieces otherwise you are stuck with the old school kidney pad and crummy shoulder straps.
Also bought MOLLE 2 shoulder straps and waist belt with my pack and they are pretty comfortable. (Top Left)
Two other modifications I did right away were add a carrying handle, just a double cobra for this. I also added some fastex buckles for the pockets and straps, a nice improvement.
Overall this is a great 3-4 day pack for me with those mods. In any event, I wanted to make this a little more comfortable and I wanted to add on a tad bit more storage. On to the bottom pics.
Directly above is a pic of my pack with my new Alipad from Highspeed gear, not only does this fill the comfort gap but it also adds two pockets between the pad and the frame which I greatly appreciate.
I also added two canteen holders for the sides, one of which holds my filter and stuff for water, as well as anything else I want.
The photo to the right shows my fastex buckle additions. It makes getting stuff a heck of a lot easier.
