Hammer Head Swim Caps, creator of the world's first patented protective swim cap, is featured on the Waterfall Racing Podcast, hosted by Ironman athlete Joy McAdams. The episode, titled "Why Every Swimmer Needs to Think About Head Protection with Hammer Head Swim Caps," explores a frequently overlooked issue in endurance and aquatic sports: protecting swimmers from accidental head impacts.
The podcast challenges athletes, parents, and coaches to reconsider the traditional swim cap as merely an accessory for hair or team logos. Instead, Hammer Head advocates for a new category of personal protective equipment (PPE) designed specifically for the water, similar to helmets in cycling or other protective gear in sports.
The interview shares the personal journey of founder and CEO Theresa Finn, whose son suffered a concussion after striking a pool wall during backstroke warm-ups. Business partner David Burns experienced a similar incident when his daughter hit her head during practice. These experiences transformed their parental concern into a mission to improve head safety across aquatic sports.
During the conversation, Finn and McAdams discuss head-impact risks such as crowded practice lanes, backstroke wall strikes, mass-start open-water swims, congested buoy turns, and rough conditions leading to athlete-to-athlete collisions. Although swimming is not traditionally viewed as a contact sport, accidental contact does happen, and Hammer Head aims to address these risks without compromising comfort, fit, or hydrodynamic performance.
"Our mission has never been simply to create another swim cap," said Finn. "It is about giving swimmers access to meaningful personal protective equipment designed for aquatic sports. Athletes protect their eyes with goggles, their skin with wetsuits, and their feet with proper footwear on the run. We believe protecting the head should become an equally natural part of preparing for the swim."
Hammer Head Swim Caps feature 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. The product maintains a streamlined, wrinkle-free profile and, after testing by Dr. Gary Hall, Sr., Olympian and founder of The Race Club, swimmers can also count on being faster and more confident, with a reduction of up to 10.5% of frontal drag compared to latex or silicone caps. It can be worn alone during training or underneath a team or race cap during competition.
The episode highlights Hammer Head's broader vision: making conversations about head protection as common in swimming and triathlon as they are in football, hockey, skiing, and cycling. The discussion extends beyond equipment to education, prevention, concussion awareness, and empowering athletes to make informed decisions about their safety. Finn concludes, "We want to leave aquatic sports safer than we found it." McAdams adds, "Prevention is always the right choice!"
The Waterfall Racing Podcast interview follows growing media interest in Hammer Head and swimmer head safety, including coverage by CBS Minnesota's WCCO, Daily Mom, Dawn of Sports, Swimming World, Parent Magazine, and SwimSwam. For more information, visit Hammer Head Swim Caps.
