 What makes the Hammer Head® Swim Cap different?

We challenged the status quo by inventing a swim cap that brings head safety to the great sport of swimming. We strongly encourage your swimmers wear during daily practice and meet warm-ups, where most head strikes occur - in busy pool lanes.

How does it help protect from impacts and collisions?

A cushion inside – invisible from the exterior – designed to help absorb and dissipate the shock from accidental and repeated collisions with the pool wall and other swimmers.

How common are head injuries in swimming?

More common than you think. Head safety of our swimmers is top of mind for parents, coaches and athletes with the implementation of Concussion Protocol Training (CPT) across all states by major organizations like USA Swimming and the National Federation of High Schools Association.

We all know of the inherent risks in swimming like novice swimmers learning the backstroke, daydreamers doing circle turns and flip turns, 5-meter flags blowing in the wind and crowded practice and warm-up lanes. All make for a greater likelihood for head strikes and injuries, especially in the young (12 & under) developing brain.

Don’t take it from us, let the statistics speak for themselves.

  • 96% of 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.
  • Hundreds of head injuries each year occur and we think one is too many!

How do I wear the Hammer Head Caps?

The Hammer Head logo always goes in the front and the cap size is labeled on the inside back of the cap. If you have long hair, make a low ponytail and tuck the hair up in the back of the cap. You can wear your team cap over the Hammer Head and maintain the smooth-wrinkle-free racing surface. Check out this brief video:

Is the Hammer Head Swim Cap more durable than other caps?

Yes. Hammer Head Swim Caps is made as one part with premium silicone and has no seems, unlike traditional latex or silicone swim caps. Because of this it outlasts other caps.

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

No. The Hammer Head comes in three sizes; small, medium and large. We know all heads are shaped differently, but please use this as a guide for your purchase. You will know you have the right size when it feels like the most comfortable cap you have ever worn!


Why does the Hammer Head Swim Cap cost more than a traditional silicone or latex cap?
