Very well made. I don't know any other manufacturer (in and around motorcycling) that makes stuff of such quality.
This is as big waist-bag as you would want to carry. Short for the camping gear, it will hold everything you need to carry on a motorcycle. A lot of different compartments. It sags a little (with 2kg of stuff in it), but this will need further field testing.
As predicted, it will not go well with an R25, but this combination would be too much gear even for a paratrooper.
Theoretically, it could work with a waist bag facing front.
I sense a Hydro pack in my future.
