Basil Unisex Adult Miles XL Pro MIK Pannier Rack Bag - Waterproof Bike Bicycle Cargo Bag, Black & Orange, 31 x 23 x 23 cm - Perfect for Commuting, Grocery Shopping & Outdoor Adventures

It is not truly waterproof, as far as I can tell. I closed all zippers and ran the shower. Water on the top eventually soaked into the interior of the bag. It has more pockets than my previous bag and fulfills the promises in its advertisements. The pockets have greater capacity and are easier to fill and empty than my previous bag.Using the zippers takes some effort. The bag could have one or more pockets on the inside. However, there are more pockets on the outside. The directions are good for most actions but need an overall statement that introduces the bag to the user. Finally, it would be good to know that to achieve waterproofing, zipping is required, not just covering with the flap on the bag.I give this bag a solid A, despite what the stars suggest.
