In a word - Wow!
Just got my Empire Builder with brain cell today. It is everything you said it would be and more. The military sends me places on a whim and they are very hard on computers and equipment. I believe this combination of bag and brain cell will make sure my laptop will make it through the dust/dirt/rain with no problem.
There is room for everything in here. I loaded it up with my computer, accesories, miscellaneous paraphenalia I need in my job and it still felt comfortable to carry.
This bag is as sturdy and well constructed as my London Bridge assault pack (That has lasted me over 10 years and numerous travels). I am looking forward to the same from my Tom Bihn bag.
Thank you to Darcy and Amy for getting it to me quickly.:)
