Bought this to replace my 20 year old Ortlieb rollltop bag as it started to walear thin and had a few see-throughs at the bottom. Guvi is always good quality and this bag nearly only half price compared to the German brand. Looks sturdy, is big and rolls up easily. Only thing I did was adding a couple of D-rings to the side fasteners, as I generally use the bag on the pillion seat strapped long side up (see pictures).
