Frequently Asked Questions

What makes the Hammer Head Swim Cap different?

We invented the world’s only protective swim cap – built for safety, but it does so much more! The Hammer Head is for all ages and skill levels. Here are the Hammer Head Swim Cap unique features and benefits.

  • HIT Honeycomb Impact Technology® – patented technology designed to reduce the shock of accidental and repetitive head strikes in the pool
  • TEKFIT® – designed with no wrinkles and built for racing
  • QUALITY – tear-resistant, premium silicone that is designed to outlast other caps

Do Hammer Head Caps look different?

They are a little longer on the sides, covering the ears and unlike a traditional silicone swim cap there are no wrinkles on the Hammer Head Swim Cap. This is a result of the patented HIT Honeycomb Impact Technology® which is invisible from the exterior.

How do I wear the Hammer Head Caps?

There is a front and a back and the logo will always go in the front of the cap. If you are a swimmer with long hair, for the best fit you will want to make a low ponytail and tuck your hair up in the back of your new Hammer Head. You can wear your team cap over the Hammer Head and maintain the smooth-wrinkle-free racing surface.

Is the Hammer Head One-Size-Fits-All?

The Hammer Head comes in three sizes; small, medium and large. Although every head is unique, generally the small fits swimmers ages 2-8, the medium ages 8-14 and the large fits an adult. Variables include size and shape of head and length of hair. You will know you have the right size when it feels like the most comfortable cap you have ever worn! Please see the shop page for specific measurements for each size.

How do I care for my Hammer Head Caps?

You can simply rinse it with soap and water occasionally and turn it inside out to dry.

How does it help protect from impacts and collisions?

A layer of honeycomb chambers – invisible from the exterior – designed to help absorb and dissipate the shock from accidental and repeated head strikes with the pool wall and other swimmers.

How common are head injuries in swimming?

Approximately 70 percent of swimmer head injuries occur during busy swim practice and in crowded warm up lanes at meets. Of all injuries, 68 percent occur from swimmer’s colliding with each other, the bottom of the pool or the pool wall.

Hammer Head has worked with instructors, coaches and parents since 2013 focusing on collaboration to increase safety in the pool as a “mutual responsibility.” It is especially critical for youth swimmers and their developing brains, as they continue to get comfortable in the water and clumsily learn their strokes.
