This rainwear was specially developed for use on the motorcycle and thus meets the highest demands on durability. It must be able to withstand very high water pressure over a long period of time. The speed driven and the intensity of the rain cause greater or lesser pressure on the material. Simple rainwear (such as those used for bicycles) are usually made of very thin nylon and cannot withstand the water pressure created when riding in the long term. Especially the seams very often prove to be a weak point in the longer use. In this model, a special seam sealing process was used and each individual seam was sealed and welded again with a heavy-duty sealing tape. The outer material is extremely strong and very stable, yet it does not restrict freedom of movement while driving. Batteries.
