The bad was good but I got the wrong product
I ordered the 11.8” version as shown on the listing but received a bag that was about 18” long. The bag was high quality and worked well but it wasn’t the size I wanted, so be careful when you order as this might happen again as I got no response from anyone about the issue.

straps way too short
Very disappointed. The straps are so short. No way to attach on a frame and headset of a modern bike. Do not buy unless using with a 1980s steel tube frame. Horrible strap design will not work with modern bikes.

Good size
Big enough to fit a roiled up top layer

Nice but not fit MNT Bike
Wish it just had some longer straps so it could mount on a MNT bike frame. Or any frame that I have.

Great Top Tube Bag Especially for the Price
I have only used this bag for one long ride on the Greenbrier River Trail but so far I really like it. I have another top tube bag that uses a boa strap and a magnetic closure. Both are cool but that bag moves all over everytime I open or close it. This bag stays secure on my gravel bike. I like that it has 3 straps and you can move the straps go. I also use a smaller frame bag so I can stagger the straps on my top tube. We got rained on multiple times and everything stayed dry inside. The zipper works well too. Its not a huge bag but I didnt want anything too big. Its big enough to hold my iPhone, small wallet and some snacks. A heck of a deal for $13!

Good large top tube for the price
Really nice bag for the price I paid at the time. A few caveats or at least answers to some peoples complaints. True, the straps it comes with won’t work on a modern frame. You can address this with longer straps of varying cost (you can get a cheap pack of velcro straps on Amazon). I went with voile nano straps which actually cost more than the bag. But I had them laying around so it was an easy fix. The bag is rock solid with these and will mount to any bike. Voile straps are my preferred method of lashing things to a bike.Only two complaints 1) not waterproof (any zippered bag without a truly waterproof zipper is going to leak) 2) zipper seems a little flimsy/rough so I wouldn’t over stuff it and then force the zipper. I see a lot of complaints on broken zippers on all sorts of products and I imagine people are just rough on them by over stuffing and then forcing the zipper. I would be extra careful with this one for that reason.For what I paid in summer 2025, this is a great bag for bikepacking rigs and a fraction of the price of similar bags.

spacious interior, looks great 👍
this half frame bike bag is big, holds plenty of stuff, installing it was pretty straight forward. right now it’s just holding hand pump, tire gauge, 2 tpu spares, 2 levers, allen tools, snacks and clears 2 water bottles.
