Such a great design. So thoughtful with a lot of very nice touches. It might be the best bag I've owned (we will see how it does in the wet).

It was pretty easy to install, it feels sturdy and can fit the average water bottle when extended. It doesnt really get in the way of your tailight. A bit hard to zip up sometimes but aside from that, i would recommend.

I just received this bag, put it on my bike and it seemed like it's sturdy. I just plan on using it to hold keys, wallet and eventually tire levers and patch kit and it seems it will be able to handle these OK. The sides near the bike seat post and the rear panel that opens do reflect back when a bright light hits it; I didn't see any incidental light reflecting back with using a LED flashlight. I let the non direct light from the flashlight hit the parts and they didn't reflect back; maybe from a further distance they would. I gave it a rating of 4 because of the reflective property, it would be nice if non direct light would reflect back as a visual warning. But overall I think the bag is nice.

Most under seat bags are too small for an epic day out with the gear that requires. I’m a bit of a bike snob so my first inclination was to buy some really nice small bike packing bags for my gravel bike. After spending way too much on other bags, one was too big for typical one day rides and the other squeaks when I ride and didn’t have a ideal mounting area for my Garmin Varia taillight, so I had to gerry rig it. I saw this bag on Amazon and it was so reasonably priced, I was a bit skeptical. Time will tell, but it appears to be well made, mounts quickly, securely attaching under my seat and to the seat tube and has a nice place for my Garmin Varia (with a clip mount) to hang off the back. Most importantly, it’s big enough to hold my tools, a light jacket rolled tightly and a spare tube and an energy bar or two. Finally, a bike bag big enough to let you carry what you need for a day’s adventure.

Happy I bought this, it's been very useful. The quality is good, and I like the expandable size and interior mesh pocket. I swap it between my mountain bike and road bike, and fits securely on both.

If you're like me, you like to leave home ready for nearly anything that can happen on the trail. This seat bag is larger than most, but I'm fine with it because I can put all sorts of stuff in there and feel confident I've got what I need with me.

I just keep getting impressed by the quality and functionality of this bag. When expanded it is enormous, but still not ridiculous. I can fit so much inside and it's water resistant, quality fabric. Would recommend.
