Review on Blue Motorcycle Seat Tail Bag Backpack - Waterproof Dual Luggage Bag for Motorbike Saddle Bags - Versatile Multifunctional Bags by Ryan Carter

Although it was 2 days late it seems just what I need to take a few things with me on a trip. It's included but I haven't used it yet as it arrived about 45 minutes after I left for the day. I love that it expands to accommodate anything I can take with me while I'm away when it's small. I expect it will withstand what a drawstring backpack can withstand.
