    Calvus Cap

    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.

    • Q & A

    What's the difference between this cap and Elaho Cap?

    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.

    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.

        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.

          • Familiarity: I've used it several times

          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

          • Familiarity: I've put it through the wringer

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

          Great hat for summer

          • Familiarity: I've used it several times

          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.

          Very Light

          • Familiarity: I've used it several times

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

          It fits my tiny head!

          • Familiarity: I've put it through the wringer

          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.

          Great hat

            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

            • Familiarity: I've put it through the wringer

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

            Witness the Fitness

              And it doesn't show sweat lines.

              Great Hat

              • Familiarity: I've put it through the wringer

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

              Great Running Cap

              • Familiarity: I've put it through the wringer

              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.
