A nice modular space. The D750 with AF-S VR 24-85, his visor and strap (neoprene) fit well. I also put in a reasonable way, a GoPro and accessories, a pole, a Gorillapod (SLR), a RX100 and some accessories (méméoires, batteries, etc).
Comfortable to use with its adjustable strap, it lacks only closed compartments on the sides to be perfect.
