The best sun hat I've ever had
- Familiarity: I've put it through the wringer
It is very light, covers completely, string under the chin keeps it on in the wind, it has vents, it is packable, although you have to be careful not to bend it in half, because foam inside will be scrunched and hat will have a strong crease in the middle. Make sure visor part is flat, when you fold it.
Sizes are very generous.
