I think it was you or someone else that asked me. I didn't look when I was over there, probably should have but the technology is still behind ours by a longshot. My guess is Mil-Tec. I don't know what French Regs are as far as non-standard issue kit...but I rarely saw anyone using something different.
I use this pack for every day use. Just to put in a uniform or some other small stuff.
It has 45L volume and it cost me only €55,00. I tried to use it with my bodyarmour but than for me the straps are to short so I have to replace them. I also had to put paracord on the zippers because the the things you pull on (ye all know what I mean) already broke.. I bought this at a local shop.
Flyye makes a similar one. Don't know the price but they could be cheaper.
They also have a separate sidepocket for this pack.
