Gome 4 You don’t need to carry a big bag if you bring only a few stuff with you. This waist bag is suitable for a brief walk in urban area.The tyre material used in this bag is unexpectedly soft. Its storage is surprisingly spacious. I could put 2 mobile phones(1 iPhone X with case + 1 iPhone 6 Plus without case), 2 wallets (1 short wallet + 1 L-shape wallet), 1 pack of chewing gum inside at one time. If you just wanna have a brief walk, a 500ml PET bottle with a short wallet is also easily fit in.However, the design would be better if they do some enhancements in later model:1) The current buckle is too large. A slimmer buckle is better for waist bag;2) there’s no inner pocket inside right now. If there’s at least one inner pocket, I could but keys or small loose object in the inner pocket without worrying that they move freely in the bag;3) if the bag could have a double zipper head, users could use a clip or tiny padlock to secure the zip head with the bag’s metal decorative hole for preventing thefts.
