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.

I wore my PURPOSE kit for a half marathon on a very hot day, and I was genuinely impressed. The cooling technology really worked — I never felt overheated during the race, which is something I’ve never experienced before in those conditions. The fit was comfortable from start to finish, and it performed exactly as I hoped. Definitely looking forward to racing in it again.
S
A splendid hat able to keep me cooling for all the half marathon with more than 31 Celsius degrees easy to restart just with a bit of fresh water! Helpful indeed
S
Was little nervous investing in the bucket hat without testing it but was super impressed once I used it - fitted perfect and definitely helped cool me down in SEA weather
L
Pva material, it is very low cost products, i guess the cost of the whole hat just 2-3 usd.

The hat helped me a lot during training and for my marathon in the singapore weather. I was able to cool down and have cold water dripping from the melted ice cubes that were a godsend when I needed it. However after 2 months of usage for training and race, the hat has a few “spots” that cannot be removed during detergent. I believe the material used could have been an issue. If you’re ok with having a spotted white hat then it’s no problem. But I think after a few more months, my hat will become even more dirty looking. A pity.

This product is amazing. It’s feels really weird when it’s dry but as soon as you wet it, it’s literally sucks the heat off your head! It got me through a half marathon in 32° heat. If you struggle in the heat, this is worth every penny!

I use the Cap at the Relay Marathon @ Callenge Roth and it was very very very cool. I put ice in the little front bag too and keep it wet on every aid station. It‘s also a good training cap under hot conditions.

Did not test it in heat yet though
M
As with other purpose running tee i’ve bought before the performancewear is exceptional as usual. Will surely buy again for new model

I find the hat sits too shallow on top of our head. When I first used it, I didn't really feel the cooling effect that much. I used cold water to soak it for the first time then went for a run. soaked it again waiting for the effect but still nothing. Probably will just use a normal running hat.
M
Absolutely great product, dealt with the Sri Lankan sun beautifully. The pocket at the front especially good allowing for ice storage between aid stations which kept my head cool the entire race as it melted. Would never be without this hat for a hot race

Superb

good material

I have to admit that the product is very good, it realy cools down your head. The size is perfect for me, but I have to say that is for medium to small heads more than for de bigger ones. The wrong part has been that de delivery to spain has been 30€ and another 18€ of customs, when thay annonce free shipping, must be for selected countries, check that or convince some friends to divide costs. The welcome discount also didnt work, they kindly give me another code to have 10€ off. To sum up, good product (still thinking that is expensive), but what has annoyed me has been the delivery. When they arrive to shops is going to explode!

Great cooling even 6-7 hours later
S
I suffer from the heat in Singapore and have tried all types of cooling items. This hat is by far the BEST COOLING HAT ON THE MARKET!! Just wet it and put it on, and it instantly makes your head feel cool. Wet it with extra cold water and it is even better! THANK YOU PURPOSE!
S
A bit pricey but great quality and fast delivery
S
This is a game changer! I wanted to put this to the test going for a 10 KM run in the Malaysian afternoon heat. I was really surprised about how cool the hat made me feel. the more I sweated the cooler it seemed to get. I now have a new hat for my races!!
M
Nothing can beat this in the heat.
Please don't put rock on your face, put only this cap on your head and...some fresh water... And enjoy your best performance in the Heat!!!!

I used the hat at the Challenge Roth and was satisfied. Unfortunately, I then had a question about the product and wrote two emails, which have remained unanswered even after 14 days. And for me, a really good product also requires good service. Hence, only two stars. It's a real shame.

Don't be fooled, this hat is so small it will never fit on a grown man's head not matter what you do. if you wear normally a l/xl running hat, do not think this will fit! and then if you order, try and navigate the return page. good luck with that. another running company that wants to make it hard to return something.

I bought my glacier cap at the Roth expo after seeing it online. The race temps in Roth were around 26 C on the run and mainly overcast. I was well heat adapted and thought the cap would provide an extra edge. I must say I never felt heat stressed the whole run and my heart rate stayed low. I really liked being able to put ice into the front pocket as putting ice into a normal cap directly on your head is not nice.
I had the fastest run in my age group as well as winning it overall and felt the glacier cap contributed to my success. Although not cheap is is cheaper then the Omious visor which appears quite fragile...
