Great, fit well.  I use them for walking, and I'm very sensitive to heat - as well as have quite sensitive skin.  I got them to replace a similar hat, and I've noticed two things about these:
1. After a while of wearing, the straw feels rough against my scalp
2. They protect well against sun in the eyes - but don't ventilate as well as my previous hat, so after 30 min of a brisk walk, my head feels hot.
