The top loader pocket is removable, so that is gone, along with all the attachment points for it. I trimmed the waist belt, lift loader and shoulder straps down to just a little over what I needed (they are all excessively long). I removed the ice axe loops and shock cords and the sleeping pad straps. I also cut away the outer portion of the outside pocket, so it still has the sleeve and mesh side pockets but not that long-ways zipper pocket ... if that makes any sense. I should post some pictures, but that would go in the gear section.
I saw a post from another member a while back who had cut away basically everything except the main compartment. I didn't go that far. I think the Flash packs are perfect for people who are just getting into lightweight backpacking and still want a few bells and whistles that come on conventional packs. The packs are so affordable, you won't feel guilty about cutting them up whenever you feel comfortable doing without some of the features. OR for people who want a cheap pack to experiment on.
