The FinFirkin is made of durable Poly Vinyl Chloride in the USA.
It will completely suspend your fin and wing when installed to keep them from being moved after you have spent hours or even days getting it set so the ski works right. Just slide the FinFirkin on after each ski set for the best protection available. A real must for skiers who travel. Lined with high quality felt where the FinFirkin contacts the ski. And after many years of manufacturing, the new FinFirkin FLOATS!!!!
