Change the way you swim thanks to the ergonomically engineered Arena The One Goggles. They feature the brand’s exclusively designed gasket, which is based on years of research into the human face, giving you the very best support and comfort as you tear through the pool. At the back, the split strap works to relieve pressure - no more unsightly red marks after leaving the pool - while the nose bridge is self-adjusting. Perfect for a triathlon, The One Goggle really is the only one for you.
