Waterproof & Lightweight Tail Bag Extension Bracket for Bikepacking

I got this because I wanted to be able to carry stuff around on my road bike. I am using it right now to tote my spare tube, toolkit and a tiny first aid pack. I plan to purchase the bag that compliments the "rack". I'll wait for another month due to my tight budget. But it's still functional. I showed my rear blinker light since it does cover up where I used to put it, but you can just put it onto the back of this! Please forgive my ratty seat!

I’ve had seat bags from a variety of different brands. They tend to be expensive, sometimes hard to mount and they don’t all fit my current bike. This one is so reasonably priced, so adaptable and so uncomplicated. A great thing!

I used it on a 100 mile gravel ride. It held my gear well and held up through that adventure. I would like to see a better attachment point on the seat post. I think a wider piece of webbing/strap would help with the security.
