Hey guys, am hoping someone can ID this bag for me. I think its ex US military, but has no labels or NSN so cant be sure. I bought it off some dude on EBay UK site few years back and it was just described as army hydration bag. It has 2 compartments, small one with 2 mesh sections and the larger can be expanded. Also has area for bladder on the back accessed by a Velcro opening near grab handle.
I Want to get another one for mountain biking you see as this one is for work, but cant find one anywhere or even a pic of one online so struggling a bit as to what it is. If anyone knows the exact name of it I would be very chuffed as I love it and can easily track one down then.
It’s a little bit bigger than a Camelbak Mule for reference.
