These are the all new long lasting formula. We tested them all last summer and they did well. All Polyform balls are warrantied for 1 year.
Polyform slalom buoys are the best. As skiers, we have been looking for better slalom buoys for years. These are the best we have found. Head and shoulders better than the cheap import specials. Especially in the Florida sun. Very durable to abuse by skis. With free shipping on orders over $100, you cannot beat this price. They are worth twice what you pay for the cheap stuff.
