Let's start with the good. The bag is waterproof, rode in the rain, nothing got wet inside. The material of the bag is great! Now for the bad. You can't operate a phone through a bag with gloves and barley without gloves. MY BIGGEST PROBLEM, with phone, wallet, keys, paper and a few other small items in the bag, it works great on tarmac, but when you're on a bumpy or gravel road, the bag just flies away. I ride my bike a lot on and off road and that's a big problem for me. The magnets are not strong enough for gravel roads or trails. I plan to open the tabs and put in stronger magnets.
