Slimmer back for under your top tube
I was looking for a bag that is slimmer to fit under my top tube. This one does, that, it’s a little too small vertically to get my wallet in, I have to kind of put it diagonal in there.The strap that goes around my top bar can be finicky to get adjusted so the end of it doesn’t rub on my leg. It could use a shorter strap on my bike. Not sure if I’ll try cutting it down or not. I don’t want a sharp velcro edge rubbing on my leg either.I’m still on a quest for the best bag to go below my top bar, this one is close and is probably going to be the one I use for awhile.I haven’t rated it for water resistance, because I haven’t had it out in the rain yet.

slim and tight
This bike frame bag fits nicely on the frame. Provides to ziper pockets. 1 pocket is slim and the other provides roam. Seems like good quality and it does not rub on legs. I recommend this bag. Good value

Disappointed by this.
Loved the under tube style and size but getting things in and out of the zipper was too much of a hassle. My riding glasses were always getting hung up and it was a pain looking for things. Zipper opening design was too small and too stiff. I got a different style that zippered across the top on one side so I could open it up fully and see what’s in the bag.

This is my tool bag
Holds a small bag of wrenches and Allen keys, a multi tool, a tube, a pump, tire levers, a psi gauge, and 1 snack bar. The snack bar helps when I have to use the other stuff. Really glad it fits.

Excellent
The triangle on my frame isn’t very big, so I use this vertically, attached to the seat tube. It perfectly fills the space between my top tube, seat tube, bottom bracket, and water bottle holder.I use it to hold my phone (iPhone 8+), wallet, keys, mini 100% deet bug spray, and a protein bar. It does not bulge with all these things.I store my tube, tire levers, and microtool in an underseat bag. I store my pump on my bike frame. I think you’d be hard pressed to fit a tube or pump in it.I attach and remove it each time I ride (again, my bike triangle won’t fit on my rack otherwise), and it is holding up just fine.Sheds mud and water really well. And it is waterproof.Works perfectly for what I need.

Nice undercarriage upgrade!
I swapped out a larger capacity bag for this to go with the packing bag I bought to hang on the saddle. It makes a good compliment for some smaller items now that I can stuff more in the “trunk”. The strap system was a bit complicated to figure out at first but it’s a sharp looking bag with a nice iridescent reflective logo, and the switch opened up more space for access to my seat post bottle cage.
