This bag is TINY. I mean...you know it's small from the pictures but man is this thing small. It's actually perfect. As shown in the video, you can get some of the latest action cameras inside and although that's about the only thing that could practically fit in this bag, it comes in handy if you need to store things like components to your action cameras, memory cards, camera lens filters and small items like that.

It has a water resistant design around the zipper so having it mounted outside your camera bag or if you were to get caught out in the rain, whatever you have inside this bag should be fine and not get wet (Alternatively you could get a ziplock sandwich bag and store whatever items you want to put in this bag in the ziplock bag first theeeen put it all in this little bag). It is sorta pricey for it's size but it's a neat and pretty durable looking bag.
