Glacier Hat – Stay Cool, Run Strong
Crush the heat, not your pace. The Glacier Hat is your secret weapon for staying cool and comfortable on every run. Engineered for endurance athletes, this high-performance cap supports your body’s natural cooling system—so you can go longer, feel better, and perform at your best, even in the heat.
Cooling Technology That Works With You
Just add water. That’s it.
The Glacier Hat activates with a quick dunk or pour, kicking off an evaporative cooling effect that pulls heat away from your head—no batteries, no gimmicks, just science. A built-in ice pocket lets you top up the chill mid-race: grab a few cubes at the aid station and keep the cool going strong.
How to Use
-
Activate: Wet the hat with water (dunk, pour, or splash).
-
Boost (Optional): Add ice cubes into the hidden inner pocket for extra cooling.
-
Perform: Slip it on and feel the difference as evaporative cooling kicks in instantly.
-
Refresh: If it starts to feel warm, simply rewet, shake it out, toss in more ice, and you’re good to go.
Note: If it starts to feel less cool, don’t worry—it’s still working. Your brain just adjusts to the sensation over time.
Why Cooling Matters for Runners
Running heats you up—sometimes to the point of reaching internal temperatures that mimic a fever! That excess heat doesn’t just slow you down—it can put your health at risk.
Enter thermoregulation: your body’s natural system for staying cool. It pumps blood to the surface and sweats out heat. When that sweat evaporates, it cools your blood, which then cools your core.
The Glacier Hat boosts this process by enhancing evaporation and shedding heat fast. The result? Greater comfort, improved safety, and better performance—because fast runners stay cool, and cool runners go fast.

Is this the best cooling hat for running in hot weather?
Yes. The combination of evaporative cooling fabric and optional ice chamber makes it one of the most effective heat-management hats available for endurance athletes.
Does the cooling hat require batteries?
No. It uses natural evaporative cooling—just water.
How long does the cooling effect last?
Depending on heat and humidity, 30–90 minutes before reactivation.
Is it safe for marathon races?
Absolutely. The ice pocket feature is specifically designed for mid-race aid station refills.

Great product, no calf issues over the Ironman. Delicate but lite
T
Disappointed with the style. Looks great in the photos but delivered with different colours and style.... Very plain looking.
Z
Very satisfied with the product. The material was really good and so breathable. Very suitable with our tropical climate.
T
The bigger holes are great, the cap is stretchy. But attention to details is lacking. Poor sewing, bad triming

Hey

Just raced IM 70.3 WC in Nice and was facing a Half Marathon in 30 degrees! And I don't like the heat. Picked one up at the Expo and credit it with keeping me alive and going on the run. Definitely kept me cool with the water and ice and a must have, even in more temperate climes.

I was charged €24 in customs duties, even though the website clearly states, "The total amount shown here includes all duties and taxes." I sent them an email about the matter, but they never replied.
J
When Cyril showed me the hat in the Roth Expo, I was initially sceptical - but when he put in on my head - wow. Pick done up immediately. And he gifted an ice towel - kudos!
Worked well on the run - the pocket to fill with ice was a godsend on a warm day!
Great hat - highly recommended

Great quality bucket hat, good design. Fast delivery
F
I run in Singapore, where it is hot and humid every day.
At first I didn't believe the marketing materials. "How can that be?" "It's probably not worth it". Until I tried it. And wow! Impressive! Once it's wet, specially if you had started with ice, it will keep you cool for a long time! Haven't tried it for a full marathon yet, but I did wet it on Saturday afternoon, and it was still cold to wear on sunday morning.

Can you make these in white?
Q
super comfy, breathable, and perfect for long rides!

I wore this bucket hat for a long weekend of triathlon fun. Great sun protection, super lightweight and breathable. A really great addition to my hat collection.
T
Definitely can’t imagine a cooler cap, except maybe one that holds ice, like their new Glacier cap. Great value and great quality. Looks great to. Recommended.

Awfully light n comfy
F
The design and the material is one of a kind which i really like . Unfortunately the sizing it a bit inconsistent since i have a few pair of T shirt and depending on what im buying, the sizes is either S or M.

Didn’t realise what I’ve been missing all these years!! I was so amazed by how comfortable it is, especially the band around the thighs and the chamois. Nothing felt too too tight, I felt supported.
J
Great for roads and trails alike
