Klein Tools 55485 Tool Bag Backpack

This is a heavy bag when empty, but extremely well balanced once you put your gear into it. I actually use that middle panel for all of my more wonky punch-down/crimpers etc. that I have to drag out on occasion. I keep the heavy hand-tools closest to the back (like any backpacker should) and the lighter stuff by " order of operation" moving rearward. The metal clip/hook allows me to secure it in the van-either to a shelf or through some rope loops I have run through the holes in the cargo wall for just such things. Be mindful though of the space and weight. This is easy to overload like a "contractor trash bag". For all the same reasons. This is the highest grade of nylon weave (1680 Denier) that I have been able to find for travel, gun bags, day packs, camera bags etc. It is an excellent build!! I love it because it does have the extra space that some other bags don't afford to allow you to set it up how you use things, and not have to play "tool Tetris". Just don't try to stuff it full. Also the gap pocket is great for a small impact driver or drill. Or a crap ton of wire, zip-ties, rags, or whatever. While kinda pricey, it is a gamechanger imho! A far better value when I compared it to a more expensive brand-which I would swear was made in the same factory.
