After many think I bought this garage. The main reason was that by means of zipper no rain, leaves or other Can penetrate through the bottom muck. Holds tight, seams are still Ok and my bike Top is protected outdoors. The material is tear resistant. I can not know better. However, be careful! The bicycle must necessarily be cooled before The tarp over it poses, because the material is completely weather resistant and waterproof though, However, the hot exhaust or engine melts immediately and are holes. Otherwise, just buy it !!!
