I first starting using the CALPAK Spider backpack as a handy down from my son; off course he needed a new backpack for every school year. I have used it now for four years on my 100 mile per day motorcycle ride to work and back. I ripped the side after getting it caught on an object in my garage, and after looking at many other styles to replace it with, I finally decided to go ahead and repurchase the same bag. It is light weight, durable, and the compartments have met my needs very well. The number one seller for me, because of my motorcycle use, was the airflow technology and the padding it provides while resting on my back. A great purchase for the price, and I believe if you want better, you will need to spend twice as much.
