Perfect tool bag

Chyna BarbzDecember 24, 2025✓ Verified purchase

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. Read more

This tool bag is amazing, for several reasons

Samuel MatthewMarch 22, 2017✓ Verified purchase

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. Read more

Sturdy, plenty of pockets, a bit tight for power tools, most importantly: It's a BACKPACK!

YourCallCannotBeConnectedAugust 30, 2023✓ Verified purchase

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. Read more

Durable, Comfortable, and Roomy Tool Backpack

ssisnowpowerSeptember 11, 2025✓ Verified purchase

The Klein Tools Tool Backpack is built tough and feels like it will last for years like my last one. The 39 pockets make it easy to organize tools, and the molded bottom keeps it standing upright and protects everything inside. The padded straps make it comfortable to carry, even when it’s fully loaded. It’s a little heavier than some other bags, but the durability and organization are worth it. A great choice for anyone in the trades who wants a reliable tool backpack. Read more

Solid bag with a tough bottom

WilsonApril 1, 2026✓ Verified purchase

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. Read more
