This is a nice size fanny pack with a plenty of room for a phone plus other things. I can put 4-5 Galaxy Note phones which are usually huge and still have some room to put keys and other small things.
I bought the grey color thinking it would be the dark grey as shown in the product picture but it's very light grey. I should have paid more attention to the customer pictures.
It seems well made. The fabric is very nice. The strap is very long, even long enough to wear this across the body.
The back has a slight padding (thicker padding than a padded bra). I don't really like that padding because it makes me sweat when it's hot and also that padded back keeps the whole bag shaped in a certain way that this bag is not too flexible. If it wasn't for that padded back, I could fit more stuff in. I know this because I've used 5 fanny packs in the last 6 years. I know what works and what doesn't (for me).
Overall, it's pretty nice for the price. I would definitely buy more but in black next time.
