Yesterday I purchased a Bumbakpak, and the first thing I noticed was how comfortable it was to carry. The straps on the Bumbakpak are configured just like a golf bag, and makes carrying it just as easy.
The Bumbakpak is made from the same type of high quality 1680 ballistic nylon like most high end suitcases. At $85, I think its priced excellent. There are similar bags being sold for over $100 that aren’t half the quality.
As to style, mine is the Biz-black, and it looks very slick b/c the orange PVC lining that peeks out a little bit. It kind of reminded me of a Jack Spade bag. Bumbakpaks are much better looking than regular backpacks. I could see a ton of young professionals, college students, or older people with bad backs using them.
