i called the UPS store and some crafts stores but cant seem to find something i can stuff into my lowepro fastpack 250 to prevent my camera body from shifting while its on my back...does anyone know where i can find this type of material? or a inexpensive way to stuff my backpack without causing potential damage? i dont really want a spongy material because it will start flaking and dont want any of the debris to be in the bag to get into lenses...i stole these pictures from a member on here for a mental idea...
or if u have any leftover material you're willing to sell to me for cheap, please PM me! thanks!
