The AeroMesh Hiking Cap fits hat circumferences of around 21.65–23.62 inches (55–60 cm). The strap-and-buckle closure at the back lets you dial in the exact fit—just slide to adjust.

You have 30 days from the day your cap arrives to send it back. Just cover the return shipping to our US warehouse, and we’ll handle the rest. That easy.

It’s not a replacement for sunscreen, but the brim does a decent job of keeping direct sun and glare out of your face while you’re out there.

Most mesh caps just add a few cutouts for airflow. AeroMesh is built with a full skeletal ventilation structure across the crown—so heat can escape instead of building up. And it doesn’t stop at “more air”: it pairs ventilation with sweat redirection, guiding moisture away from the eye zone instead of letting it run straight down.

Yes. AeroMesh was designed for high-volume, heavy sweaters. It doesn’t try to “out-absorb” your sweat (that always saturates). It focuses on what actually holds up: venting heat to slow the flood, then redirecting what forms so it doesn’t become a constant eyes-and-wiping problem.

Absolutely. A lot of our hikers are bald or shaved, and the AeroMesh works just as well without hair underneath. The interior lining sits smooth against the scalp and the cap handles sweat the same way regardless. Just make sure you pair it with sunscreen on any exposed skin—if you’ve got hair, that’s already doing the job for you.

The ventilation openings across the crown are engineered to be wide enough for airflow but small enough that it’s not something you need to worry about. You’re getting maximum breathability without turning your cap into an open window.
