Please note - this is not a review written the day after the product arrived.  I bought this bag about 6 months ago.  It was replacing a big bulky bag that I had for 4 years with absolutely no problems.  I decided to replace it with something that distributes the weight better and is easier on my shoulders.  As a mechanical engineer and an artist, I like the design of the Access backpack.  As an engineer who travels through a lot of asian factories, however, I can tell the supplier snuck one past High Sierra.  Manufacturers in asia will often use a cheaper product to save some cost and tell their customer it is the correct material.  If High Sierra doesn't have a Quality Engineer watching over their shoulders, the manufacturers will do it all of the time.  Anyway, in this case, someone used a cheap thread when sewing these bags together.  My bag is coming apart at the seams in numerous places and one of the side support straps is half torn.  I do not over-stuff my bag and I do not have a big, heavy computer.  I load this bag with about 80% of what I used to put in my big bulky bag.  This backpack should handle it with no problem.  Lastly, the zipper on the bottom (holds an odd and never-used rain cover for the backpack) is constantly unzipping.  I'd rather have a place to add straps on the bottom so I can strap on other items during my travels (coat, pillow, etc).  I'll buy another of these but as soon as I see a seam coming apart, I'll be sending it back.
