I'm heading out to a desert climate and am concerned about walking around in the heat with my loaded film holders… Does anyone have any suggestions for bags that would work for carrying about 8-10 8x10 holders, ideally with a shoulder strap? I've seen some camera bags that might be boxy enough for this purpose, but I have a feeling there are some that aren't originally intended for camera equipment that might actually work better.

Suggestions greatly appreciated. Thanks.
