To trim precious seconds off of your swim split, the Orca Killa Speed Goggles can do the trick. Hydrodynamically-tuned lenses may not sound like a big deal, but youd be surprised how much drag is generated by traditional blocky goggle designs. The lenses are further treated with an anti-fog coating, and the ergonomically-shaped soft TPE rubber gaskets attach seamlessly to them for excellent leak-proof comfort. The strap is clip-adjustable. Available in dark clear or light mirror cosmetic finishes.
