The cap material is bonded to the outer mesh structure and the lining is a dense mesh-like structure that absorbs sweat well! It looks like a running hat, but it is also suitable for summer hiking! Since the brim is a hard material, it seems that you can choose it if you do not like the shape of the soft brim material. However, if you are looking for the comfort of a hat because it is too comfortable to wear by using a soft material brim cap, I think it would be good to choose the soft shell brim cap for Heo Gye-yong: Crushin It Cap, Vaporlite Cap, and Ultra Trail Cap! However, since the brim is made of hard material, it is not as comfortable as a soft cap, but it is 1.5cm to 3cm wider and longer than the brim length or other general hats, which is good for awnings.
