Hammer Head Swim Cap
How do I measure for the right Hammer Head size?
It’s easy. Just measure the circumference of the head about 1 inch above the ears — that’s the sweet spot for an accurate fit.
For racing or a more compressed feel, wear your team cap over your Hammer Head and goggles. This gives you our signature smooth, wrinkle-free dome for maximum speed and hydrodynamics.
For the best comfort and performance, wear your Hammer Head with the logo centered in front. That’s how the cap is engineered to fit just right.
Hammer Head is designed to look sleek, smooth, and streamlined in the water. The protective honeycomb layer is hidden inside, so all you’ll see on the outside is a clean, wrinkle-free — not a bulky helmet.
It fits just like a high-performance swim cap, only better:
No wrinkles that slow you down
No bulky shape or awkward profile
A smooth, hydrodynamic silhouette that looks fast and feels even faster
Most divers say it’s the best-looking cap they’ve ever worn — and the most confidence-boosting.
Protection you can’t see. Performance you can feel.
Hammer Head underwent drop testing by ACT Labs, the global consumer product testing lab, and was proven to reduce impact force by more than 50% compared to silicone and dome caps — making it the safest cap in the water.
But we didn’t stop at safety.
Olympic legend and performance expert Dr. Gary Hall, Sr. tested Hammer Head for drag reduction and found it to be up to 10.5% faster than traditional wrinkled silicone or latex caps. That’s the power of our wrinkle-free Honeycomb Impact Technology.
We strongly recommend wearing it in practice, meet warm-ups, and competition — because protection and performance belong in every lap.
Why does Hammer Head® cost more than a traditional silicone or latex cap?
Because it’s engineered to do more — and last far longer.
Most silicone caps cost $10–$15, but swimmers typically burn through 4–5 per year, spending $40–$75 annually on caps that tear, stretch, or wear out.
Hammer Head is $34.95 and built to last years, not months. That makes it the smarter long-term value and the only cap that delivers four game-changing benefits:
Head Safety, Speed, Comfort and Durability!
Aquatic sports have embraced innovation in tech suits, goggles, training gear, and nutrition. It’s time we all expect more from a swim cap — and Hammer Head is the next evolution.
The Hammer Head logo always goes in the front and the cap size is labeled on the inside back of the cap.
How do I care for my Hammer Head?
After each swim, simply rinse your Hammer Head and turn it inside out to dry completely. Avoid contact with sharp objects that could puncture the cap — treat it well, and it will deliver long-lasting performance.
