FASTEST AND SAFEST

Ideal for racing, the Hammer Head® cap is safe, wrinkle-free, hydrodynamic, and reduces drag. Hammer Head® is the ONLY protective swim cap, and provides the best competitive advantage in the water.

  • TEKFIT® – new hydrodynamic wrinkle-free dome shaped design, achieving a reduction in frontal drag compared to a standard silicone cap
  • HIT Honeycomb Impact Technology® – patented technology designed to reduce the shock of repetitive and accidental head strikes in the pool
  • QUALITY – made with one solid piece of molded 100% premium silicone, tear resistant, and outlasts other caps 

 

SWIM FASTER

Hammer Head® Swim Caps improve hydrodynamic performance in the water and reduce drag in competition.

  • Hammer Head's proprietary TEKFIT® cut is designed for the human head. Our caps are larger in the back than in front, and are available in three different sizes to ensure the perfect fit.
  • Perfect for competition, Hammer Head caps' dome silicone design in combination with honeycomb structure guarantees a smooth, wrinkle-free experience with unmatched hydrodynamic efficiency. 
  • With HIT® safety technology, swimmers can feel confident giving their full effort without worry of accidental collisions, allowing them to focus exclusively on speed.
“In addition to being safer, Hammer Head helps my client’s racing performance. Whether it’s actually putting numbers to the science, or the feel behind the cap — swimmers can tell when putting the Hammer Head cap on, they are faster.”
– Abbie Fish, Expert Technique Coach at USA Swimming High Performance Department

THE WORLD'S ONLY PROTECTIVE SWIM CAP

Hammer Head is the next generation of swim caps. All other sports require protective headgear, it's time swimming catches up.   

  • HIT Honeycomb Impact Technology® is a revolutionary addition to swim cap design, protecting against accidental and repetitive head strikes in the pool. 
  • Tiny honeycomb pillars provide an invisible protective layer, absorbing the shock from any impact with a pool wall or other swimmers. 
  • Enhancing performance and helping Hammer Head® caps stay wrinkle-free, HIT® introduces the only major safety innovation in swim cap design in over 100 years.   
"Hammer Head the safest, fastest, most comfortable and longest lasting swim cap in the world. My BREAKOUT clinics will have the best interest of the swimmers in mind being protected by Hammer Head Swim Caps."     
– Josh Davis, Olympic Gold Medalist and Founder of BREAKOUT! Swim Clinic
    
"It’s a simple but essential piece of safety equipment for every swimmer." 
– Rowdy Gaines, Three Time Olympic Champion 
      

FEEL THE DIFFERENCE

Made from a seamless, flexible, premium silicone, Hammer Head® caps are designed to be the most comfortable and durable cap a swimmer will ever wear.

  • Hammer Head® Swim Caps are created with a single piece of 100% premium silicone compression mold, delivering a seamless and smooth finished product.
  • Unlike other swim caps, Hammer Head caps are built to last for years and will not rip or tear. 
  • Designed for comfort and flexibility, TEKFIT® and HIT® protection set a new standard for how a swim cap should feel. 
“I got the feeling that the honeycomb technology reduced heat loss without making my head feel sweaty or hot. Normally I can feel the motion of the water against my skull through my swim cap, but I think the hydrodynamic properties of your cap removed the feel, and it was actually quite pleasant.”   
– Melissa Wieser, Triathlete

Aquatic sports athlete’s head circumference (measured above the ears) ranging from 19" to 22" will provide the best fit.

Elite Competitive Swimmer Testimonials

"There is a reason we wear a helmet when cycling. There is a reason we wear lights and reflective clothing while running at dusk or later. There is also a reason we should wear a protective swim cap when training and competing in the water. Mass swim starts are insane and for all of us who get knocked in the head by another swimmer knows how crazy you feel for the rest of the race! When weather makes waters rough other swimmers and kayaks blow on top of us. Hammer Head can make a huge difference. Keep safety top of mind!"

Joy McAdams

Ironman Competitor and Momx5

"Safety is of the utmost importance in our sport - emotional, mental and physical. I am excited to align with Hammer Head who shares the same who values. You gotta check them out! Hammer Head the safest, fastest, most comfortable and longest lasting swim cap in the world."

Josh Davis

Olympic Gold Medalist, and former world record-holder, NCAA DII Head Swim Coach and Founder of BREAKOUT! Swim Clinic

"In a drag study test we found that by wearing this new technology at top race speed, compared to wearing a conventional silicone cap, passive drag force was reduced by up to 10.5%. So, in a 33 second 50 meter freestyle tenths of seconds can be shaved. That is certainly enough to win (or not win) a race." Checkout my 4 tips on how to swim faster video!

Dr. Gary Hall Sr.
3x Olympic Medalist and Founder of The Race Club

"As a researcher and head safety advocate, protecting your head and optimizing head safety is critical to maintaining brain health throughout every stage of life, but particularly from youth to young adulthood when the brain is undergoing development. During these formative years of brain maturation, sustaining concussions can have a lasting impact on your overall health. Ensuring you are protecting your head while improving your fitness can only produce everlasting benefits that are beyond the arena of the pool. Hammer Head's innovative swim cap provides you with a honeycomb technology that absorbs and distributes the force of a head collision to reduce the impact that your brain could ultimately sustain. I highly recommend this cap as this is the world's first protective swim cap and there are no other products like Hammer Head." Click to learn more.

And for the first time ever, Hammer Head combines head protection that is 50% safer than other caps, performance that can improve your speed up to 0.6 seconds in a 50 free and seamless durability that will outlast any other cap!"

"Hammer Head is critical for head safety in Triathlete competition mass starts. Besides really appreciating the additional head protection, I love the
hydrodynamic design and comfortable fit. I feel faster and more confident in the water."

"As athletes' race through open water, they have limited visibility as water and other athletes splash all around. The waters can be particularly dangerous during the mass starts and in traffic jams at buoy turns. In rough waters, officials are in boats and kayaks in close proximity to the swimmers, creating a hazardous environment. That is where Hammer Head comes in. Make it part of your standard equipment list....it is the least you can to do protect yourself."

Quinn Fitzgerald

CEO of World Open Water Swimming Association

"Everyday we make choices to help keep our children safe and healthy. We choose to make them wear seat belts in the car, helmets on bikes, and look both ways before they cross the street. So, why wouldn't we provide them with head safety technology inside their swim cap as they enter swim lessons and swim competition? There is no other swimming cap in the world like Hammer Head."

Swim Parent Testimonials

"My daughter has suffered 2 concussions already because of running into other kids while swimming so I am very interested in getting her something to protect her head."

Karen

Swim Mom

"My 8-year old daughter Brooke hit her head when racing the backstroke three years ago. It was such a strong impact that I could hear the gasps of other spectators. She didn’t swim the backstroke for two years and she still is apprehensive. If Brooke had been wearing Hammer Head, I’m confident that the impact of hitting the pool wall wouldn’t have affected her as it did."

Angie Lubenow

Swim Mom

"My 15-year-old daughter suffered a serious concussion at high school swim practice when she collided with another swimmer and it took her 6-7 months of rehab to recover. I think Hammer Head is a fantastic product that gave her the confidence to get back in the pool to do what she loves. It is wonderful!!!"

Heather

Swim Mom

"Most recently we employed a mandate on our Junior level athletes to wear Hammer Head swim caps during practice and at meets."

Chris DahowskiHead Coach

Senior II, ASCA 4, Paseo Aquatics & Swim Parent

"I have seen a number of concussion accidents happen during regular synchronized swimming practices and competitions, even during a Pan American event. Her team practices 14 hrs per week and we don't want to take any chances. The Hammer Head has been used extensively and is still in good shape, looks good and very comfortable. My daughters’ teammates on the National Team purchased one after they tried her cap. As an elite athlete, you need to do what what you can to stay protected."

"Summer League Swimming is all about community, water safety and fun.  Too often water safety is focused on learning to swim, but not providing protection for ongoing safety. Hammer Head has patented an incredible product that increases safety during practice, meet warm-ups and during races."

Franke Marsden

"Throughout my time swimming and coaching, I’ve seen far too many incidents of swimmers getting hurt and I have personally known girls who have got concussions from being kicked in the head because it is such a contact sport. The Hammer Head Swim Cap would be awesome for girls to wear during practices as an added measure of safety."
