I bought this bag for my tools at work in the foundry. I have had several other bags most being duffle bag style this one being the second backpack style. This bag is the best one I've purchased so far. At first, I was a bit skeptical. I didn't know if I'd be able to get all of my tools in there and fit it in my locker at work, but it all works. The thing I like about this bag is everything seems heavy duty right down to the material used. I also love the way I can organize my gear in this bag especially considering the odd gear I carry for all of the jobs I do. Most of my work bags last about a year but we will see with this one it looks tougher than the usual work bag I buy.Update: I bought this bag in 2020, it's 2023 now and I'm still using it. The bag still looks really good. I broke the plastic clip for the waist strap but didn't really need that anyway. The straps are still perfect. The handles are still perfect. I put lots of weight in there too. The bag still has no holes. The pockets on the inside are still perfect. The outer pockets are also in perfect shape. The zipper for the main compartment is worn and doesn't zip all of the way up anymore. I do overload the bag though and that has put more stress on the zipper than you normally would. The zipper is the only thing that has me thinking about getting a new one but I think I might keep using this one and see how long it stays as good as it is. I am extremely impressed by the bag! I never in a million years would've expected it to last this long let alone stay as nice as it has. You can't ask for a better bag.
