Review for Customized Medium VELO Backpack
I love this backpack. It's been great for commuting in summer heat, with or without a laptop. Holds everything you might need for a day at work -- lunch, umbrella, sweater, notebook, etc -- without looking or feeling bulky. Can fit a bike helmet in it as well. The seatbelt straps are comfortable in my experience although I haven't loaded the bag down too much.
