Simply Fab
I bought this in a rush as I needed a secure waterproof bag for a winter break in NYC. It was great! Nice & roomy, very secure & no leaks in one very rainy day. It doesn’t budge if you swing round your back for cycling. I haven’t tried it on my handle bars as yet, will wait for better weather. I didn’t receive it next day due to my location but still arrived within 3 working days which was great.
