Great Track Back Protector

June 12, 2010

I purchased this back protector three seasons ago, and it's still in great condition. Its slim design fits comfortably under both my one-piece and two-piece suits. It offers good ventilation under my one-piece suit with venting aerodynamic hump. A track necessity, and a street benefit.

I would recommend this item to a friend.
