Review on CamGo Bike Seat Pack: Waterproof Cycling Storage Bag with Reflective Stripe – Ultimate Wedge Saddle Bag for Tools & Accessories by Derick Johns

I bought this case to replace my old case which was too small to fit my Galaxy S8 in a case. So I switched to this one and was not disappointed. The zipped compartment opens nice and wide and has room for my phone, backup light, my keys, folded mask and some extra space. It has small mesh pockets so nothing bounces around. The zip tabs were easy to grab and use. There's even a handy loop for a tail light. I used it in the rain with no problems. The attachment system is flexible and uses Velcro but attaches securely. My previous bag required an allen wrench to attach it to the seat mounts so this bag installed in literally 30 seconds. So if you need to take it off and take it inside with you, that's no problem. Not bad for under $20.
