Looking for Computer Sleeve w/Strap Hooks

Does anyone have any suggestions for a computer sleeve for a MBP 15" that has the hooks on the outside so that I can attach a shoulder strap directly to the sleeve and use it to carry the MBP around? Many of the sleeves I have found do not have the hooks and are only meant to protect inside of another bag. I like the convenience of being able to take the sleeve only with me if I need to.

Thanks!
