The Arc'teryx Calvus Cap is a light hat optimized for weather protection while you're running. Its air-permeable, stretchy fabric is incredibly breathable to help you keep your cool on long runs, and Arc'teryx treated the fabric for weather resistance whether it's rainy, windy, or sunny. Mesh side panels amplify ventilated airflow, and the Spacermesh sweatback wicks moisture and dries quickly for active-focused comfort.
- Light protects from weather while trail running
- DWR-treated Socora fabric offers durable weather-resistance
- Polydel mesh sides amplify airflow and ventilation
- Spacermesh sweatband wicks moisture and dries quickly

Excellent Running Hiking Hat
I have a hard time finding hats that fit my large dome. This one fit me well in L/XL and comes down low enough. Its comfortable and wicks well.

Love this hat
This is the best hiking/running hat ever, and the L/XL fits my large head better than any other hat has. I just wish that Arcteryx made them in more colors each year.

Love the fit
The smaller size of the cap fits comfortably and size of the adjustable strap is small enough that it does not flap when riding my bike.

Nice hat, like the look and the material. Got one for my husband and one for me. It looks awesome on my husband. It looks good on me but the cut is a bit too deep (if this makes sense). It sits on the head behind ears which make them to stick out:) I just wish it fit above the ears and not behind them. Otherwise, great hat.

I have been very pleased with both the fit of this hat and the cool feel of it. It does not trap heat underneath, and the strap holds securely without causing any discomfort.

Cooler heads prevail.
This hat does a great job keeping your head cool, while making you look cool. It doesn't get soaked during a sweaty run, and washes easily.

Extremely comfortable and breathable
My wife loves this hat and says it is the most comfortable and breathable "cap" that she has ever owned.

Great hat for summer
Bought this for my wife, who spends a lot of time outdoors in the summer. She likes how it is cool, lightweight, and has a place for her ponytail.

Superlight running hat, the bill is long so if you do not run with sunglasses this will suffice.

It fits my tiny head!
It fits perfectly, is lightweight in hot weather, and still, just keeps my ears tucked in when it’s really sunny on cliffs or in the garden.

Only wish more colors - comfortable, warm but breathes. Wear on most runs except the extreme cold or hot. Nails everything in between for me.

Light and Comfortable
I wear this hat for everything from trail running to splitboarding. It's light, I love the material, and it fits well.

Very lightweight and comfortable. Dries extremely quick and you forget that you are wearing it.

Great Running Cap
The cap is light and comfortable even though I sweat like crazy during my trail running race in Thailand (close to 40c). Love the fact that it is washable.

Awesome fitness cap
This has become my go to for running and ski touring. Vents like nothing else I have tried; obviously get the white to stay cool in the sun. Weighs nearly nothing and is washable.

Pay attention to color
Make note that the mesh panels on the blue hat are powder blue. Otherwise, solid hat.

What's the difference between this cap and Elaho Cap?
June 12, 2019
The main differences will be the function and purpose. This hat is designed for running, it has a DWR coating to shed light rain, it has mesh side panels to allow for maximum breathability and it includes a sweatband inside. Weight 50g. The Elaho is designed for packability. Hiking or travel are the main purposes. It includes a UPF rating of 50+. Weight 45g.
