Available in three sizes: S, M, and L for the perfect fit

To make the most of the lightness and softness, a good fit is very important.

The original model was only available in one size, but we have updated it to offer three sizes: S, M, and L so that more hikers can wear it comfortably.

Size design to find the "just right"


Everyone has different head shapes and preferences for how they wear their heads.

It is designed with a balance that naturally suits those who want a light, shallow fit, as well as those who want a tighter fit.

Our goal was to create a cap that would feel comfortable the moment you put it on, no matter what size you choose.

Find the size that suits you and looks great.


The well-balanced shape provides an airy, stress-free fit and a beautiful silhouette as a cap.

Available in three sizes, you can find the perfect fit for you.

Fine-tuned strap construction


Each size can be adjusted within a range of approximately ±2cm from the standard head circumference (R).

The strap can be neatly stored inside the cap body , so it doesn't spoil the appearance and doesn't get caught on a backpack.

A size that is easy to choose even if it does not overlap


So you can choose with confidence, even online.

The balance between head circumference (R) and height (H) is clearly indicated, so by comparing it with the cap you normally wear, it is easy to imagine the size even if you don't wear it .

The light and soft merino wool body gently envelops subtle individual differences , ensuring a comfortable fit.

R = Round (head circumference) / H = High (height)
