http://www.ospreypacks.com/travel/departure.html http://www.intermountaintraders.com/store/Osprey_Synchro_25_Backpack.html I landed the above two packs brand new at a close out sale. The big pack will easily hold a REALLY large camera . Of course the wife is against that idea. Oh well, it will hold all of my LF 4x5 and and 5x7 stuff on trips. Now I need to find the foam stuff to make them into photo packs. Where can I get the stuff that is in Pelican cases or dividers like in other bags? Any direction will be good. I would like to stay away from regular foam padding if I can.
