Because I have had skin cancers removed from my ears, I MUST wear a hat (and sunscreen -- don't forget your ears). I've worn this model for nine years, hiking in California and hiking and paddling in Maine. The chin strap is a must. I've had to paddle hard for hats blown off on the water. After almost a decade and several effective scrubs with dish soap, my Pathfinder Breezer, while still comfortable and functional, is just too stained for anywhere but the garden. Time for a new one!
