Swim Cap Beginnings

Swim caps were originally invented to keep hair dry and to protect hair from chlorine and chemicals. Some pools began requiring caps to reduce maintenance with their filters. As they evolved, new versions were designed to help competitive swimmers streamline through the water by reducing frontal drag to swim faster. But, until now, there has not been a swimming cap to help protect aquatic athlete's heads when accidents occur.

Head Injury Risks in All Aquatic Sports

Whether it is a backstroke swimmer miss-counting at the 5-meter flag and slamming into the pool wall or colliding with another swimmer in busy warm-up lanes, a triathlete entering the water in a mass competition start, an Artistic swimmer base launching the flier into an acrobatic move and hoping for an accurate landing, a diver entering the pool incorrectly at 25 MPH or a water polo goalie repeatedly heading the ball, there is a need to protect these heads like all other sports do for their athletes.

Concussion & Head Injury Awareness, Statistics and Legislation

National Governing Bodies (NGB's) recognize the frequency and seriousness of head injuries, which is why USA Swimming, USA Triathlon, USA Artistic Swimming, USA Diving and USA Water Polo have all implemented mandates and concussion training certifications in an effort to make aquatic sports safer for their athletes. If reported, these are all moves in the right direction although they are all reactive to an injury. In high school alone, medical professionals report around 2 million concussions per year. Unfortunately, head hits occur above and below the water and often never get reported. For more information, visit Swimming World Magazine.

A Look At The Stats & Trends

• 96% of swimmer head injuries at meets are during warm-ups and cool-downs

• 73% of all head injuries in practice occur from collisions with other swimmers and the wall. Visit Swim Swam to learn about the 6 stages suggested for returning to the pool after an injury. 

Artistic Swimmers have a higher risk of head injuries than other aquatic sports

Triathletes have head injury risks at mass swim starts, in rough waters and on the cycling leg of the race. In fact, World Open Water Swimming Association (WOWSA) nominated Hammer Head as "2021 Product of the Year"

Divers risk head injuries when hitting the platform, spring board or when they enter the water with poor form

Water Polo tracks the perils of concussion injuries
