Holds plenty of things, primarily I use it for travel, serves as an extra big wallet keep the passport, cash, sunglasses, headphones, keys all other little essentials like that together rather than rooting around in my backpack. Swap out the straps if needed, essential RFiD pocket, happy with everything and you can see the quality in the build. Smashing, give it a go. Can also double as a handlebar bag for the bike. Excellent.
