This bag has the new bicycle inner tube reinforcing, padding and a separated main compartment so you can fit your laptop and the power supply, mouse and other peripherals.

This is the first bag with a custom printed panel - super slick. 

This prototype fits a 17 inch screen Macbook Pro, the final Sisu ones are to fit Dell 15.4inch widescreens (and my T61p Thinkpad :-))
