pic help because I'm bored.
Anyway, I have the proteus seen here
I use it to strap to the bottom of my edc pack when I use it for more serious hikes for extra room for supplies. Dunno what info exactly you want, but maxped is pretty bombproof, functions as advertised in general, costs kind of a lot, and people either love it, hate it, or are indifferent
If you've seen one in person and feel the size is right, you'll likely have no complaints quality-wise etc
