This is such a good product. The bag is so well thought through and I've had a lot of compliments on it. It works great as a day festival bag, I never have to worry about my phone, keys etc, and the amount of pockets inside is great for bits like cash, card, ID.
I really only have 2 criticisms. The bag itself is maybe half a centimetre too small to fit a 500ml bottle in - I tried a few different ones; but only rigid ones, not a flexible one. I got around this though, by just attaching it to the rope (which is an easy alternative to putting it inside, and it saves space anyway). However, the carabiners can be quite fiddly to undo. On a sunny festival day where you have suncream and sweat on your hands, it took a while to take the rope off.
Having said that, this is still a really good handy bag that I get a lot of interest on!
