Locking sailcloth.

A picture of the blue test-Versatile (spring 2004), while
the one I ordered waits for one molded piece that has been delayed by a broken mold.
The sailcloth that locks the velomobile is probably similar to what kayakers would call
a skirt. It can be removed completely for summer or somewhat opened and turned back to the inside and held in place with velcro. In front, in the center, is a zipper that one can pull closed while riding if it's too cold. Behind the rider is another transverse zipper (the two form a "T"). To close it up completely, when you get out, you pull the back flap over the front part and close a velcro fastening.
