Sidepockets are almost half the height of the bag allowing you to carry items such as larger water bottles without worry of them falling out and a strap that goes across the top of the side of the bag can be used to secure items like tripods in place.
The bag has sliplock webbing loops on the outside of the bag that provide 50 attachment points for your gear. It's also bundled with attachment accessories such as a water bottle holder, accessory holder and a tripod foot holder and strap.
The size of the bag will be enough to hold most common mirrorless setups without wasting extra space. The small size also allows it to be easily used when traveling. When flying, for example, it will fit easily in the storage compartment above your head or under the seat with room to spare.
While the strap is seemingly wide enough for comfortable use the inner liner is thin and the so the force is not distributed across the whole width of the strap. That in addition to the placement of straps being slightly further apart than usual makes the bag uncomfortable after a couple of hours...
