DV Hardware has published a review of the Spire Edge laptop sleeve.

The Spire Edge on the other hand is just a light-weight sleeve, there's no room for anything else but your notebook. It's designed to travel light, you can take it under your arm but you can also use it to better protect your laptop in your backpack. The sleeve will protect your laptop from damage and will make sure it doesn't get dirty.
