I am a recent owner of an Empire Builder with the British Racing Green cover. And a Brain Cell. I had it slung over my shoulder and behind me as I was wending my way across campus in Ann Arbor one icy morning recently. I slipped and fell on my backside and on my Tom Bihn bag with my laptop inside. It was a great cushion -- not even a bruise or a scuff on the bag and the laptop (three years old) is working fine. Thanks for a sterling product.
