The belt bag is more spacious than I thought. I don't have a charger so I can put my Osmo Pocket in my belt pouch. The fanny pack has enough space for my phone in the back pocket, my Mavic in the pocket, and the Osmo pocket is also neatly in the pocket. It's just perfect when I can (especially during this pandemic) just do a test hike. This is really what I need. The bag is so spacious that I can even put my RX100 in it. It's good to know that I have all the necessary equipment with me in a small belt pouch.
