Large Storage Space: Standard capacity of 23L. It can be expanded to 35L. When fully expanded, it can fit a full-face helmet easily and worry-free with the lockable zipper.
Fully waterproof: Comes with a separate inner bag made of enforced polyester fabric with waterproof rating of PU6000MM, and the seams are sealed with thermal welds waterproof rubber tape that can effectively resist rain.
Made to last: The main body is made of thickened and stiffened EVA, which is mouldable and shock-absorbent.
I have had this bag on the bike for about a month now,
The good: the fit is good and is user friendly to get it set up. It is well designed with zip and hard lid closure with plenty of smaller storage options as well to compartmentalise your kit. This exact same item is on Ali express / temu etc for less than 1/2 price of what is advertised here, so I have likely over paid for some drop shipped trash.
This seems to be ok, little disappointed for the price with the finish quality.
The bad: zips are tight, especially the side pockets and bind easily.
The finish seems questionable, the rubberised decal is already flaking off and the bike lives in a garage when not being ridden, doesn’t affect usability but does not bode well.
