Professional Tool Reviews for Pros

Klein Tradesman Pro Organizer Backpack 55421-BP Review

I have a friend who is an apprenticing electrician. He’s always interested in the latest tools I’m checking out, particularly when it crosses into his world (I had him take a look at the Masterforce Cordless Band Saw we reviewed last year, for example). A little while ago, however, he brought me his own tool submission—a Klein Tradesman Pro Organizer Backpack. I hadn’t even realized Klein made backpacks, though after this review I was no longer surprised.

Looks Good and Well-built

The backpack is, first and foremost, built from ballistic nylon, but in a lighter weight, 1680 denier. That’s not as strong as, say, a suitcase, but it’s also a lot lighter and more pliable (something you’d want in a backpack you’re going to tote around all day long). There are enough pockets in this thing to carry a small army of electrician’s tools (not that a plumber or HVAC tech couldn’t equally benefit from the myriad of compartments and storage areas.


Klein Tradesman Pro Organizer Backpack Features

The zippers are sturdy and the stitching looks to be quite durable as well. The color scheme is excellent and also purposeful. When you open up the backpack you are greeted to black pockets on an orange background. The result is that you instantly see your tools—they pop, for easy identification. And the pockets are very well thought-out and logical as well. I had ample space for placing Klein screwdrivers, pliers, cutters and even my concrete drill bits…and that was just on one side. Opposite that I stored a digital multimeter, Channellock E-Series XLT pliers, razor knife, and tons of other hand tools.


The outside of the backpack is equally versatile, and I used the large front pocket to hold a Klein 100′ fiberglass fish tape, which I could remove easily by unclipping two fast-release clasps. There are side pencil pockets and a loop to hang your electrical and/or teflon tape. On the right side there is also a metal flat bar that allows you to securely clip your favorite tape measure right to the bag. There are 39 pockets in all, and none of them seem wasted. Two of the interior pockets have flaps with hook & loop fasteners, in the event you want to place loose items within that might otherwise fall out when the bag is set down or opened.


And all of it can be set right down in a puddle of muddy dirt, thanks to the almost sneaker-like molded bottom Klein placed on the backpack. It not only covers the entire base, it rides up about 1-1/2″ to make sure you don’t get any seepage and ruin any of your more sensitive tools.


Portability and Use

Carrying the bag is easy and very comfortable. The shoulder straps are well-padded and there is even a handle on top to allow you to manhandle the bag and quickly pick it up or move it about with ease. I also liked how there was a lot of space within the back to allow for drills and other bulky items to be placed within, among your pocketed hand tools. This is going to be great for electricians who want to carry along some 12V or compact 18V drills and impact drivers for their day-to-day use.



There isn’t a lot to not like about the Klein Tradesman Pro Organizer Backpack—and a lot to love. It’s well laid-out, comfortable to sear, and designed with the tradesman (particularly) in mind. Because it’s so adjustable, it fit well with both my tall friend, and my own average frame. Given the ample interior space and the apparent durability of the base and interior stitching, I think this is a product that will last many years, even under rigorous job site use and abuse. Highly recommended.
