I use a cap to keep the sun off my face on summer runs. I was looking for a cap that might not get too sweaty but this one still does: the fabric is very light and the mesh panels must improve ventilation but the sweat still gathers. The cap has washed well and is still nicely bright white. I have quite a big head for a small lady but the crown is deep enough, almost too big. The brim is a good length to shade your face.
