I have been using Facom tools and bags for 15 years. I had a backpack that I wore out with daily use, and it was time for me to get a shoulder bag because now I mostly drive. It has a lot of space and is sturdy in construction. A colleague who has the same one but from a different brand (equally expensive) told me that there are huge differences in quality and that Facom looks more durable. As for the point where the zipper is held, I think all these types of bags have that.
P.S. The place where I bought it told me to hold it by the two straps it has and not by the central one

The specific bag is similar to another brand's with the difference being in the color and fabric. It is not worth the money it costs, and because I also work with the other brand, I prefer its cheaper variation, which seems to be more durable.

Very high quality, from the fabric to the seams, and very practical in terms of internal pockets - compartments for tools.
I would prefer the main handle to be a little wider.
A major negative point, which was also mentioned by the friend below (I considered it perhaps exaggerated or a mistake in a specific part), is the zippers on the main compartments, which do indeed get stuck and you have to put your hand inside to pull the fabric that gets caught in the zipper in order to open it. Otherwise, it will tear in the first few openings.
UNACCEPTABLE for a company like Facom, if they had sewn it internally, like the outer sides, it would not have been an issue.
I had to play the "seamstress" for 2.5 hours to sew it internally with thick thread and shoe awl, since a sewing machine doesn't fit, in order to make it open and close properly.

Absolutely helpful and of very good quality construction. The only flaw is that the main zippers "stumble" at two points during opening (one on the right and one on the left) and there they need special care.
