Up till now I've been using a jansport backpack while biking. I use it in conjunction with my Tom Binh Brain Cell for laptop protection.
I'll be needing a new one son since this one is running out o time (4years+ of use).
Since you'll ride bikes more than I do, I was wondering what is recommended in terms of backpacks (or messenger bags?) that can carry laptops too.
Keep in mind, I'll be needing some space since I'll be riding to and from campus with the days worth of materials most of the time.
