[This review was collected as part of a promotion.] I took this on a cross country trip for a control system install, this has a inside pocket for a 16in laptop which was perfect, it fit my laptop notebooks, small tools and even a water bottle on the job site. I was rather impressed and would highly recommend to anyone.

[This review was collected as part of a promotion.] In an Electrical Engineering Technologies Program and I used this back pack to carry all my books and school supplies as well as my laptop and some tools. It worked excellent! It is a very heavy duty bag with lots of storage compartments. Over the summer I used it as a day pack and was able to carry heavy loads very comfortably. I really liked the chest strap. Excellent quality back pack that could be used by a technician from any field.

[This review was collected as part of a promotion.] Not your kids backpack! Although you could let your kids carry their books and stuff to school; this backpack was built for the working man/woman! . From the padding for the back to the space capacity this back pack has it, to its heavy duty construction. Over all, by far the best back pack I have ever used; the first thing I noticed was the space this backpack had. When I transferred everything from my old backpack to this one I still had room to spare and pack more stuff in it. (My old backpack was busting at the seams literally, hence the reason for a new one.)

[This review was collected as part of a promotion.] This product gets an A+ for innovation and design. Multiple different pockets, slots, and zips to satisfy your tool/gear/cable storage needs. Vented foam padding on the back is amazing. Offers great support and takes a lot of the pressure off the back. Also, has two front buckles (waist and chest) that hold the pack very snug against your body. Takes a lot of the hanging weight from your shoulders. Great for hiking, mountain climbing, and biking, etc. The main storage compartment is a draw-string closure (""Rucksack design""). And there is a top flap cover for the rucksack that also doubles as another storage zip-up pocket. The front of the rucksack also has zip-up pocket for cables and other items. I keep my back brace in there -- this backpack is very versatile and can be used in multiple variations. Does NOT have a molded-rubber base -- that would be a plus. Would like to be able to set this on the ground without it folding on top of itself -- that is the only negative. Have to lay it on the ground, it is not made to be set on its base. Does have the patented storm drains in the bottom so if dust, dirt, water, other grime gets in your bag, it can be easily emptied out. 2 side pockets, 1 is a mesh water-bottle holder. The other is a zip-up for tools or gloves or whatever your case may be. Like I said, its a very innovative, versatile, general-duty backpack.Comes with D-rings on the shoulder straps and another D-ring on the side to hang your grabbers. OR WHATEVER YOUR CASE MAY BE! INNOVATIVE --- VERSATILE.Get one, you won't be disappointed. Beats any Nike, Adidas, or other brand backpack you can find. Competes (surprisingly well) with the ""best on the market"" Oakley backpack which I have. You really will get your bang for your buck with this one.
