This is a great, low visibility backpack that does not draw unwanted attention like a more "tactical bag". Such discretion was my main concern for purchase (I live in California...enough said ha ha). Bag is well made and roomy. I can get my 12" HP Spectre laptop in it. Concealed carry pocket is decent size and carries anything from my glock 19 to the tiny Sig 380. Well organized admin pockets, good zippers and pulls. I am also a medic and appreciate the lower section for trauma supplies. I did opt to use 5.5" shears for a better fit however. Also have a pack of quick clot, Israeli bandage (4" is best in this pack), SWAT T and sandwiched in some 4x4's, gloves, small roll of duct tape and HALO's. Overall very happy with it. If I had to make changes: I would add elastic to the sternum strap for shock absorption like most bags do, make the bottom of the main compartment thicker/more durable so my trauma supplies don't poke through, more padding on shoulder straps (very thin) and add mesh pockets to each side for quick access to water, or other items. Very good bag however for the purpose it is designed for.
