Maxpidition Monsoon Gearslinger 16lt Urban Tactical Bag.
Maxpidition call their packs & pouches Hard Use Gear and they ain’t pulling any punches when it comes to construction.
Made from 1000 Denier Ballistic Nylon with reinforced double stitched stress points , Mill Spec Nylon webbing straps, Duraflex buckles and YKK zippers.
Just to give you an idea of how tough their bags really are the bag in the pic is mine , its 3 maybe 4 years old , it’s well used, and apart from some minor scratches to the side buckles from rocks, it looks better now than when I got it.
Lots of good reviews on YouTube.
UK price around £130
