I work in underground mining and I take this backpack into some pretty rough environments. Overall it is awesome and very tough. It has survived being covered in dirt, drops from the back of a truck, thrown around, and even being dropped in 2’ deep mud. In the case of the mud I simply took my tools out, cleaned the mud off with a pressure washer and let it dry out.The ONLY downside to this backpack are the zippers. Once you get them to the bottom they can be a pain to zip up. If there is any dirt whatsoever in the teeth then good luck zipping the bag up. Maybe one other gripe; when the bag is open and the sides are down it isn’t completely stable and can tip over.Overall it’s a pretty hardcore tool backpack and takes a beating.The inside pockets rip from sharper tools like screwdrivers and needle noses, and the posture of the backpack over sometime will sort of start flopping over if you put heavier tools in which you will, but overall the backpack is greatAmazing product. But, once you put your tools in the pockets there is no room for other tools to be stored in it. You gotta hand carry them out.Perfect for my toolsPerfect for quick repairsAmazing tool backpack and awesome quality, will last for many years to come, not to mention the camo is awesome as well.Buena inversion, es practicamente nueva. Buenos materialesExcelenteI've been using this for a month. An excellent bag. Frees up my hands for other tools. Well made and designed. I particularly like the way it folds out to present my tools ready for use. I use it as a servicing bag. I am a gas engineer so it's not only for electricians.this is what i needed for a long time just perfectThe best quality backpack on the market for the price! Compared this to my CK magma back pack and it’s a night and day difference.This bag does not match the advertised picture. It's basically a brown bag. The orange looks more like light brown. The green is very minimal. I absolutely love the design in the picture, but the real product is a real disappointment in terms of actual design. Otherwise the build quality looks good.Great bag
