Perfect tool bag
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.

This tool bag is amazing, for several reasons
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.

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

Durable, Comfortable, and Roomy Tool Backpack
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.

Creo que es la mejor version de la mochila para herramientas de Klein Tools que he usado. Es firme no se doblan las paredes, caben las baterias de 7A de los taladros m12, en sus bolsillos con tapas. No necesito compartimiento dedicado para una laptop, porque la laptop la guardo en un bolso protector y entra perfectamente entre las herramientas. Es un todo terreno. Es la mejor inversion que he hecho del mes.

Al día de hoy, todo está excelente. Está muy cómoda, y sus bolsillos se ven resistentes. Por fuera, se ve imponente y atractiva. Es una pena que no tenga una funda extra para guardar una laptop, pero no quita mérito de que es una buenísima opción de compra. Estoy satisfecho por la mochila.

We ordered three of these for work and we are very satisfied. I wanted to compare this bag to the Veto Pro Pack so I ordered one for work. The Veto Pro Pack is a great bag but way too expensive for what you get. This Klein bag is built with durable material, has lots of pockets and won't bust your wallet. After comparing the two, I ordered another Klein for myself at home. Very satisfied.
