With two open cell foam layers to gently sandwich your laptop, a ridged aluminum body and reinforced metal corners you get 360 degree impact protection for your laptop. Adjustable rubber padded baffles allow you to create your own divisions within the case by cutting the foam and arranging the baffles. The case is large enough to hold most 17" laptops but they would fill the case leaving little room for accessories. With smaller laptops you can use the included baffles to segregate various items in your case. We recommend this case for smaller laptops because even with a 15" Mac Book Pro there isn't enough room for a power supply. The Lab also has dual combination locks and a comfortable handle.
