Get it!
Husband bought it for work to replace his Milwaukee tool book bag and he has loved it! Super durable, has many organizing pockets to insert tools and not scattered around. It does have some weight to it (gave myself a bruise trying to carry the darn thing with his tools inside lol) but thats the least. Definitely recommend if you are looking to purchase.

Perfect Jobsite Bag
The FLEX stack pack is a well made, durable backpack. All four sides are reenforced materials that will protect your items that are inside. There are various slots and zipper pockets to hold and organize your tools. There is even an area to house a laptop computer. I like that each main opening is tethered to hold the flap in place, almost like a little table allowing you to place tools while you are working. I would recommend this for anyone needing tools while working in a mobile environment. This should be able to hold everything you will need.

Fantastic backpack, just what I needed
I'm an athletic trainer and use a Flex Stack Pack for my sideline kit, so I already have several of the components. For other sports I transition my AED into the Stack Pack compact case and used to stick it inside a "tactical" backpack which took up a lot of space. When I saw a picture of this backpack, I knew it would be perfect.It is very well built; the zippers are heavy duty. It has multiple compartments and pockets for holding all of my supplies; especially since my AED is not inside the bag. I like the hard shell front and the rigid bottom that helps it stand upright if I don't have my AED attached. I also love the neutral colors. It even has a side pocket that holds my water bottle.Overall I'm very pleased and hope to get several years of use out of it

Scratched, dirty, bent shell.
Bag design is great. Love it.What's disappointing is the shell part is scratched/ dirty in multiple locations, 1 place bent a tiny bit inwards.

Holds my tools and lunch well
Great bag as far as what I needed it for.holds my tools and my lunch. My only complaint is the hard bottom hurts my lower back. Pointy and ruff. Needs to be rounded.
