I’ve not had a lot of experience using it yet, but I’m pleased thus far. Looks good with a lower profile. Strapping system to mount is solid with options. Easy access side pockets are amply sized. Despite its low profile it can hold quite a bit of gear. Along with my hard case panniers I could carry quite a lot of gear. The outer material is not waterproof. They provide an interior bag that is cut to mirror exterior dimensions and it has a draw string closure. I road in pouring rain on my BMW 1100 RT with no problems of water getting in. I also have their clip on tank bag and I’m impressed by the design and quality of SW Mototech builds. I’d recommend their products
