I do not have any affiliation with this company.  I received these at a discounted price for my honest and unbiased review, and to say I am very happy with this very well made and durable backpack.  It really does not take long for backpack to start falling apart, but this one is excellent.  The quality that went into this is beyond my expectations.  It has many pockets which is great for all the little things, not including the binders.  The zippers are well done, and some zip both ways.  The material is great nice and thick.  There are numerous buckles the also helps keep it secure, even if you zippers open the buckles helps keep the pockets closed.  You also get a buckle in the front on you chest which help with the weight.  The inside has a nice backing against you back to help even out the weight of your back. Love the design, I have 3 older sons whom are in the military and now their young bother has the same design as their packs.  The buckles snap easily and hold well, plus easy to unclip, which is great for my son.  He loves it, and has filled it up already for our hike thru the woods.  It hold many things, from school supplies, to hiking supplies.  This pack will be making a trip to Disney.
