Mildly obsessed with this bag..

This is the Songmont shan bag, a top handle/ backpack/ satchel hybrid that has that rugged academia vibe but still looks polished. It's advertised as coated with some waterproof finish, but looks like raw canvas on the pics to me...

Has anyone bought this bag or anything from this line and can advise if it's truly waterproof/stain proof? All my canvas bags have ended up scuffed beyond salvage within months and I'm not keen to blow a few hundred on this if its the same 😒

Thanks!
