MVP discs have a unique over-molded edge that is soft and tacky yet allows flexibility and firmness in the body.  A softer outside edge will aid in grabbing the chains and dropping into the basket.  The edge where the flight plate meets the rim is rounded, providing a comfortable grip so your fingers conform to the disc.

For the Eclipse (Glow in the dark) discs, MVP uses the brightest glow mixture available and heavily concentrates it in the bright white overmold rim for a stellar night glow effect. They are BRIGHT! 

Proton plastic is produced with some of the most durable plastics in the industry. It has immense abrasion resistance from impact resulting in very slow wear and very long life. It is produced with bright, vivid transparent colors. Proton plastic has such great clarity and durability because the central core is not contaminated with any weighting agents like most conventional golf discs. The weight products are placed in the outer ring to enhance the GYRO™ Technology and maintain polymer purity in the central core so that the beautiful colors are always vivid and clear.  Another unique advantage of the polyurethane MVP uses is the vast variety of flexibility.  Ions are available in Medium and Soft.

Neutron plastic (new 07/12) is a polymer blend that offers a premium look and feel while maintaining the excellent durability of Proton plastic. This unique blend offers a wide variety of bright opaque fluorescent colors easy-to-spot in any terrain.  Neutron is your go-to polymer for continued reliable performance in all conditions.
