Hammer Head® Swim Caps by Mako International LLC designs, makes and markets the world's only protective swim cap for swimmers, synchronized swimmers, triathletes and lovers of water sports. Caps feature patented HIT™ protection (honeycomb impact technology), tiny honeycomb pillars that absorb the shock of impact with other swimmers or the pool wall. Hammer Head® Swim Caps are the next evolution in swim cap design - until now unchanged for almost a century. All Hammer Head® Swim Camps also feature TEKFIT™, an evolved fit to match the real shape of the human head, eliminating top of cap wrinkles for reduced drag in the pool and sitting lower over swimmers' ears to help protect against swimmers' ear infections.
