1. Will this fit a 15"...
1. Will this fit a 15" MacBook Pro?
2. Is there extra room for the MacBook Pro to be in a protective sleeve?
3. is the interior a non-scratch material? I am wondering if I needed a protective sleeve for the laptop?
The Arc'teryx Blade 15 will fit a 15" lappy nicely, the sleeve is adjustable so you can make it fit exactly, and not have the computer bounce around. I've used mine without a protective sleeve, and the combo of a snug sleeve, smooth nylon and foam padded back and bottom, have kept my rig looking good.
