For best performance and comfort, wear your Hammer Head Swim Cap with the logo centered in front. That’s exactly how the cap is engineered to fit, protect, and perform.
Long Hair Demo
Long Hair. Don't Care.
For swimmers with long hair, pull it into a low ponytail at the back of your head and gently tuck your hair up inside the back of your cap. This helps create our signature smooth dome and ensures a comfortable, secure fit.
Your hair tucked in the back of your Hammer Head cap keeps bulk out of the crown of the head, allowing the cap to sit smoothly and evenly where protection is engineered and needed most.
Your Hammer Head should feel secure, smooth, and surprisingly comfortable — not tight, not loose. When it fits right, you’ll forget you’re wearing it… until you feel the confidence it gives you.
