I contacted customer service after purchase a junk bag elsewhere. I was looking for a good bag that I can take to classes that would hold 2-3 classes of books and protect my laptop. This bag is it, unfortunately my laptop is 15.6 inches and the super padded compartment is for a 15in computer. No worries tho, the entire bag is extremely well made. This thing sits so comfortably on my back that having 30 lbs in it is a breeze. I'd take this bag with me on a day hike on the AT any day. MOLLE webbing is stitched all the way out, the back panel is well vented. The hydration pouch is equipped with velcro and the manufacturer sells a holster to fit virtually any handgun if you conceal carry. I used to field test bags for AFSOC and I can tell you this bag is very well made. Throw in the manufacturer lifetime warranty (after you register it) and you CANNOT go wrong.
