Tough rugged quality
Best tool bag box I've ever had , the quality is superb, you can tell it's built to last. It looks almost impossible to damage too , I can't fault it . I get comments and people admiring it, I've tried many tool boxes and changed to a backpack style and won't ever go back now .

Before you commit to Veto
I would highly recommend this product, the bag is solid with good back pads. Its a good length, I found the veto to tall and I'm 6ft 2". The unit is light weight and comfortable to carry. Although I see no need to the chest strap other than to get in the way. The Veto equivalent is heavy, even to an uncomfortable level of just putting it on empty. The Klein is even a nice design for going up enclosed ladders. Havent had enough time to test the zipper strength, but it cant be worse than a CK bag. Ideal storage space except there is a lack of small zipped pockets for crimps/bottle seals/fittings. The pockets are nicely organised for a good assortment of different sized tools and enough space at the bottom for a few small items. I've got a mag valve, small bacho socket set and a wera screw driver set and I could probably fit in some other bits. The hard case at the front is a decent size for valuables, not big enough for a label maker. The front pouch below I cant personally find a use for, maybe some folded up permits or some extra spanners if needed. I got it for £90 like new using an amazon refurbish (Basically new bag, damaged packaging). This way I prevent paying the £30 delivery that was making me question the choice. Money well spent.

Quality
This bag is quality,a little expensive but you get what you pay for.Best feature is it zips both sides right down to the base virtually in half so you can get to all your tools with ease, no piling tools on top of tools or having to empty the bag to get to the tool in the bottom.

Worth the money
Twice the price from anything from Stanley or CK but it's twice the bag. Enough pockets for everything a electrician will need

Slim and sturdy
This is a very well made backpack, the seams and zippers are tough and they promise a long life, if you dont kick the bag around ofc. The most "delicate" point is probably the end of the zippers where it makes an awkward curve at the finish in order to be more accessible to the tools at the bottom. Although you can use the bag without unzipping it all the way and still have great reach to all tools except the ones at the bottom where i choose to store the most rare used ones so for me its not a big problem. It can handle ALOT of weight without anything rip or tear and it feels real good to my back while carrying it without feeling the weight even when i do 20-30 mins of walk with it fully packed. If you carry alot of tools (who doesnt :) ) you'll find that although it fits all you dont have much storage space for small parts for service but that depends on your profession, i can live with it. After having tried most backpacks i can find in my country i settled with this because for me its the perfect balance between storage space and volume to carry.

Probably one of the best tool bags for a sparky
These are fantastic! Solid zips, loads of pockets. Nice thick construction and a hard base! I can fit all of the important hand tools to do most small jobs. They are expensive but they are fantastic

Bomb proof
A great well made bag that is more than capable of lasting on site, hesitated for a while due to the cost. But as soon as I received it I was pleased I made the purchase, the materials used to make the bag are top notch you would have to seriously try hard to damage it.
