A Minnesota company that makes a patented protective swim cap is using a podcast appearance to argue that swimmers and triathletes should treat head protection as a standard part of preparing for the water, not an afterthought.
Hammer Head Swim Caps is featured on the Waterfall Racing Podcast, hosted by Ironman athlete Joy McAdams, in an episode titled "Why Every Swimmer Needs to Think About Head Protection with Hammer Head Swim Caps." The conversation challenges athletes, parents and coaches to see a swim cap as more than an accessory for holding hair in place or displaying a team logo or race number.
The company's case rests on personal experience. Founder and CEO Theresa Finn's son suffered a concussion after striking a pool wall during backstroke warm-ups. Business partner David Burns' daughter hit her head on a pool wall at practice, and another young swimmer later sustained a concussion in a separate accident. Those events turned parental concern into a mission to improve head safety across aquatic sports.
The episode details where such impacts can occur: crowded practice and warm-up lanes, backstroke wall strikes, mass-start open-water swims, congested buoy turns, and rough or low-visibility conditions that lead to athlete-to-athlete collisions. Although swimming is not traditionally viewed as a contact sport, accidental contact does happen.
"Our mission has never been simply to create another swim cap," Finn said. "It is about giving swimmers access to meaningful personal protective equipment designed for aquatic sports." She compared the idea to goggles for the eyes, wetsuits for the skin and proper footwear on the run, arguing head protection should become an equally natural part of swim preparation.
The product uses patented Honeycomb Impact Technology, an integrated cushioning structure engineered to absorb and disperse impact forces. In independent drop testing by ACT in Long Beach, CA, Hammer Head reduced impact force to the top of the head by more than 50% compared with conventional silicone and dome-style swim caps, according to the company. After testing by Dr. Gary Hall, Sr., Olympian and founder of The Race Club, swimmers can also count on a reduction of up to 10.5% of frontal drag compared with latex or silicone caps, the company said. It can be worn alone in training or under a team or race cap in competition.
The implications reach beyond one product. Hammer Head is working to establish a new category of aquatic PPE and to make conversations about head protection as common in swimming and triathlon as they are in football, hockey, skiing and cycling. The discussion also covers education, prevention, concussion awareness and helping athletes make informed safety decisions. "We want to leave aquatic sports safer than we found it," Finn said. McAdams added, "Prevention is always the right choice!"
For parents, coaches and race organizers, the episode raises questions about safety standards in sports where head impacts are rarely discussed. The company notes its caps are designed to help minimize the force of certain head impacts but cannot prevent all head injuries or concussions.

The interview follows growing media interest in swimmer head safety, including coverage by CBS Minnesota's WCCO, Daily Mom, Dawn of Sports, Swimming World, Parent Magazine and SwimSwam.
