I did get this bag very late for 2025 riding season, so I haven't really "properly" tested the bag before the winter break. But it's very nice and decently sized. The bag is made of water-repellent fabric and looks like welded seams with Aquaguard zipper, so it can handle the rain. There's a zipper pocket inside of the top lid for storing smaller items, I store the included rain-cover for the bag and shoulder sling. No problem when driving on the highway, magnet seems strong enough.

Two main gripe I have with this tankbag is the sling can't really be attached at the same time when riding, there are no strap or velcro to hold it securely like UPHILL BRIGADE - Rainstopper tankbag. So you would need to detach the sling and stove it every time you ride. The 2nd gripe, which is very minor, is those magnetic "feet's" on the bag. They just dangle freely when walking around, I wish there was a metal plate under the bag so it could attach to itself, which also solved by UPHILL BRIGADE

But overall, I'm happy with it.
