ABSTRACT:
A windscreen is described that is selectively mountable to snow ski poles for use by the skier as a screen against the elements when riding on a ski chair lift. The windscreen sheet is also flexible and may be rolled to a storage condition about one of the ski poles. Fasteners are provided to selectively secure the sheet to the ski poles such that the skier may hold the screen in an expanded, operative orientation. The fasteners may also be released to facilitate rolling of the sheet onto one of the poles and securing the rolled sheet in position on the pole for storage and transport on the downhill run. The fasteners are further provided to selectively secure the sheet to the poles against axial motion thereon.
