I fell in love with the colors and shapes of the Crumpler bags. Like the name too. I saw them at the Photo show at the Javits and went to Spring street to get a look at the whole line. I decided that a cube-shaped bag would be perfect for my digital camera and it came home with me. Big mistake. The strap doesn't stay put on my shoulder (I have been carrying camera bags since the 1970's) and I can't figure out why. The bag is nicely made and it has lots of soft stuff inside to cosset my goods. But I hate carrying it and it sits at home.
Lesson here - bring the stuff you want to carry and try carrying it around the shop. Like said, the stuff seems great but the execution may not be.
Also, remember, a bright bag attracts attention from crooks.
