Bags. These Shootsac bags seem to be perfect for the photographer who prefers to carry his/her camera(s) on their shoulders and just needs a bag to carry some extra lenses.
They can be stylish as it comes (even on men):
And, they can be ramped up with an interchangeable cover:
Made of "wet-suit grade neoprene" and designed to "[conform] to the exact shape of your glass" it looks like it would be flexible enough to mold to your body.
I've read enough comments and reviews to seriously consider purchasing one (as a gift!). In our house one can never have enough bags.
We even have what is called a "bag demo": a "show" that happens after you've scored a cool new bag and want to show all your photographer friends. I'm not sure which of our friends/colleagues, David or Vince or Bill who introduced us to our first "bag demo"...
Boy, I just got all sentimental.
