    • Perfect tool bag

The media could not be loaded. I bought this tool backpack for my husband, who is an electrician, and he really likes it. It holds all of his tools with no problem and has plenty of pockets to keep everything organized. The bag is lightweight, very comfortable to wear, and well made. It’s a great option for anyone who needs to carry tools daily. Easy to use. Lots of pockets. Sturdy he's had it for a long time and still looks good. ... 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

    • Sturdy, plenty of pockets, a bit tight for power tools, most importantly: It's a BACKPACK!
Style: Low Profile
Finding tool bags is tough. You want one that's durable, roomy, and easy to carry but accessible once you get to work and open it up. Klein makes good tools, and they've made a good bag. The most important feature is you can carry it on your back, so walking a block or two won't strain a shoulder like a regular bag would. The only issue I have is the updated design went to a zip pocket on the front, instead of the big buckled pocket. The buckled design was better because it gave you extra space for carrying larger items (like a drill or impact). It's the only reason I give it 4 stars is because the change in design is a step backwards imo. The side flaps on that pocket also prevent the front from opening in any practical manner. I cut them off and cauterized the loose edges. ... show more

    • The tool bag for real tradesmen and tool bag sluts like me!
Style: Low Profile
I’m a product line manager and was at a field test site at an international airport when one of the tradesman assigned to my team walked in with one of these bags filled with about 80 pounds of tools. Recognizing a fellow tool bag slut like myself we started talking features and I was hooked - bought mine before the conversation was done. Start with the flat rigid rubberized bottom to keep the bag upright, contents dry, and prevent “poke through” - it just gets better and better. The padded shoulder straps are not just sewn into the bag seam - they are mega reinforced onto structural tabs that go into the bag and have a chest cross strap to hold things in place. The two outer pockets on the back have heavy duty zippers and the top one is reinforced to hold delicate gear but most people will probably use for cell phones and cords. Love the METAL loop on the side to hold a tape measure tab! The bag opens to the tool storage area with two bi-directional heavy duty zippers - none of the cheap single zipper crap here. Open it a little or a lot and the zippers hold in place. Perfect for holding that tool that’s just a couple inches too long for the bag. On both sides there are Kevlar style material pockets with Velcro tabs for multi-tools, folding knives, hex kits, bits and drivers. Add to that plenty of reinforced loops to hold pliers, wrenches and the like. Whomever designed this bag has definitely lived the life and walked the walk! They did their research and talked to tradesmen about our needs, wants and disappointments. Guys - THIS is the bag you want to generate envy amongst your work buddies. Ladies - THiS is the gift you want to get for your guy to prove that you “get” him (and to get back at him for rolling his eyes every time you wander off into a purse or shoe discussion with your friends). Get the point across to your Neanderthal partner that this is the Prada, Kate Spade or Laboutin of tool bags! ... show more

    • Solid bag with a tough bottom
Style: Low Profile
solid bag. I needed something I could use to carry all of my tools for a convention, without going the Packout route. This was perfect for just that, 40lbs in a backpack is so much better than hand carrying everything. Zippers appear to be robust and it has a lot of organization for all my screw drivers, and L-wrenches. ... show more
