I wanted something waterproof, that could hold a decent amount (tube, gu, money, mini tool) where i could get what i needed out, without having to squish my fingers trying to find it. This is nice since its bright (for passing cars), and allows for plenty of room to fit what i needed.

I was looking for a replacement bag for my gravel bike, after the zipper broke, and wanted one without a zipper, that was also waterproof, the Ortlieb bag fit the bill perfectly, and was a great buy!

I bought the medium. Plenty of room for tubes, CO2s, a generous tool kit, and even a snack. The mounting is very secure, and dry bag design allows for expansion or compression as needed.

I ride a bike with a 44 frame. Many items don't fit, but this one does and is roomy enough for what I'm taking along - without being too big causing me to be tempted to overfill.

Had to return as size small not aero.

I really like the mounting system. I use a small bag on short rides and the click and remove system is really hand. It also holds a lot for an under seat bag. A part of shoes and a rain shell fit with room to spare. I bought this for a two day ride and I think it will work great.

I bought this bag in order to avoid riding with a backpack to work. It perfectly fits spare clothing to wear in office. Cant go shopping with it but, that is not a purpose. Its small enough and you can adjust its volume based on your stuff you put in there with a couple of straps.

The bag is well made and designed, but it's just too wide. I was looking for a decent waterproof bag for underneath the seat, but this is wider than the saddle itself. If you want to carry luggage, this is a good choice, but it is NOT a simple spare tube and multitool carrier. High marks for the mounting system idea, although it can be a bit annoying to figure out (and I'm a pretty competent mechanic). I put it on my city bike instead of where I originally planned to mount it.

Although this would be an incredible seat bag for the money (almost as large as some bikepacking seat bags), I actually purchased a pair to mount on the front fork of my bike to act as mini waterproof panniers. The construction is top notch and the roll top design is awesome.

My old bag was always slipping off and getting in the way, but when you wanted to take it off it was a real process. This bag is well designed for size, closure and attachment while also having good looks.

These bags come in 3 sizes- 4 if you include the micro. I bought the medium. I have a micro. Good option. Small wouldn't have been much difference from the micro, and large is huge. I can fit a lot in here. The downside is that my legs sometimes rub against it, as it is wide. It has the bolt on mount with quick release, and also a velcro strap around the seatpost. Holds firm.

Great place to stow a jacket or vest after it warms up.
I like the idea of a roll-up closure to keep the bag smaller when not full. But I do have a little bit of a problem trying to roll it up and stuff inside getting caught up in the roll. I actually cut a small piece of plastic which I keep inside to hold stuff out of the way as I roll it up works great.

I ordered this bag to be my around town bag for a gravel commuter rando bike and I wanted something large enough for a couple of 650b x 47 tubes and all the tools necessary for a serious adventure. This bag fits the bill pretty nicely, It is roomy, light and mounts extremely securely. In use so far it is quite waterproof and seems very well made. My only caution is that the nose of this bag is fairly wide and square which unfortunately means I regularly have thigh rub. This will depend on seating position and body geometry, so It is well worth a trial fitting (you can fiddle with the seat rail attachment point a bit to minimize this).
Final verdict is that this is a very nice bag, well made and attractive. My only niggle is that the nose could stand to be 12 to 1 narrower, but that may not affect all users.

Holds plenty without being too cumbersome. Tried the relevate brand - too bulky and awkward. Use it on my gravel bike - nice to have the extra room for clothing etc.

Incredibly easy to install and use. Verified waterproof. Medium bag is quite large.

Got specifically to de century rides where I haul my own nutrition and often have to lose a jacket, leg and arm warmers etc during a ride. Added advantage it's waterproof when the ride turns wet.
Review by Hodawg
The only complaint is that if bag is full can't sealed it. They need to seal with zipper or Velcro to have a secure bag while cycling.

As others have noted, these are big bags. I used the large size to carry the following on a century last weekend (as it warmed up, I was removing layers) jacket, arm & knee warmers, liner gloves, beanie, two tubes, two CO2 cartridges & inflator, tire irons, patch kit, multi-tool, torque key for carbon bars. Simple mounting to saddle, very easy to get into to addremove stuff during the ride. Note that there are no dividers inside, I pack my tools in a padded mailing envelope so they don't rattle. Much easier to access than the usual small zipper bag. I will probably purchase at least one more.
