Review on 🚲 MOOZO Waterproof Water Bottle Bag: Under Seat Bike Saddle Bag with Double Bottle Pouch for MTB, Road Bike, and Repair Tools Kit by Andrew Dinelli

The straps attached to the seatpost are quite strong. Straps that go through the seat rails don't slide well. until it hits the frame. In the absence of better fasteners, this 4-star bag becomes a 2-star bag. I wonder if they've ever tested them with full water bottles. If the manufacturer is reading this, be aware that the rail straps are too thin for the snaps (or buckles) used, and the guide straps just slip through. If you fix this please send me a replacement. If there wasn't a flaw, this bag would be very good!
