They are the worst. Seriously. I tried and tried to like them. I don't mind them when I am walking - I really prefer them for graduate school since I have to carry so many papers to/from, but on my back during a ride, no thanks. I even bought a super nice one designed for my commute. But no.

I feel like a freak because everyone seems to like them, but I don't. Can't stand to have something that big on my back. Gah. I feel almost suffocated.

Anyone else share this? My backpack is uber supportive, but I just feel constricted.

I guess it is back to shoving the pack into my second bucket pannier.
