The fabric of the sail is as expected. A coarse plastic Masch work which, in my opinion precisely the requirements which you can have by the product description does justice. However can be improved the supplied fixing ropes. This dröseln on already at the first mounting attempts. You can also go the ropes knot difficult. The material is easy to like PVC. One of performed nodes, in whatever form tends to be working again. The material is easy to smooth, slippery. I'm not a sailor who hinbekommt an expert Sehmannsknoten, but a decent string would here certainly more success. :-)
