  • The perfect tool backpack
Style: Low Profile
Have been using the older style for years. While i loved it, it quickly started slouching. Hoping this new model will work better. Other brands make nicer backpacks, but this one is much lighter. It's JUST big enough to hold all my bare bones as an electrician. The tape measure holder is really loose for some reason. Still deserves 5 stars ... show more

  • This tool bag is amazing, for several reasons
Style: Low Profile
This tool bag is amazing, for several reasons. The first and foremost being it's seemingly endless pockets and sections for pliars, screwdrivers, wrenches, ratchets, etc. the second reason being its durability and resistance to scratches and tears. I have dropped This bag, thrown this bag, drug this bag up against block walls and everything else under the sun, and its material has held up. It feels sturdy and well constructed because it is sturdy and well constructed. Klein very rarely slips on quality, and this is no exception. I will say there's not a lot of room that's not designated by a Velcro pouch or a pocket of some allocation. You can't really open it up and toss things in it, as with a standard tool bag. Some feel this important because it forces unorganized people such as myself to stay organized. The bag is a bit stiff when you get it, but after a few days of working it It will loosen up nicely. This is definitely a great buy if you're in a field such as electrical work and need specific tools in specific places. The shoulder straps are nicely padded and it makes walking around for long periods of time toting this bag comfortable, even if it feels like it weighs half a ton because it's full of linemen's pliars and screwdrivers. And hey, it's always nice to have two free hands for whatever you need to carry in addition to the tool bag. This is definitely worth the money if you're in need of a sturdy bag that can work as hard as you do. ... show more

My boyfriend does hvac and has been through many backpacks. This one is wonderful. It keeps his tools organized and in one place. He says it is comfortable, big enough for what he needs and the quality is amazing. He’s had it for two years now.

Only giving 4 stars because I recently broke the zipper after 2 years of heavy use but overall would recommend 👌 it is a backpack so keep in mind you have to carry it on ur back. ... show more

  • Durable and spacious
Style: Full-size
This backpack is HEAVY DUTY. I got it as a gift for my son-in-law and filled it with tools so he could start a new trade. I was extremely impressed with the space this bag provided. I'm also impressed with the durability and construction. There are plenty of pockets inside and out. I bought all the tools he needed and still had room for plenty more. I don't travel with my tools but if I did, I'd certainly buy another one of these backpacks for my tools. If you're weighing the options, pull the trigger on this. It's well worth the price. ... show more
