The opening stage of a triathlon can quickly devolve into a turbulent mess, with hordes of racers threatening to slow you down with all the thrashing and splashing. Maintaining clear vision during hectic races and open water training, the TYR Blackhawk Racing Polarized Swim Goggles maximize optical clarity by filtering out glare and maintaining a watertight seal. The polarized lens blocks harmful UVA and UVB rays while eliminating distracting glare under the bright sun. Durafit Silicone Gaskets ensure a tight, yet comfortable seal that's watertight. Other swim-savvy features include five interchangeable nosebridges for a custom fit and a wide peripheral design for maximum vision in open water.
