I rarely rave about any product but my Tula hat is a phenomenal piece of head gear for paddling. It is made of hand-woven palm and the quality of construction is top rate. It has a 4" brim along with a UPF 50+ rating so it really provides excellent protection from the sun. The cotton foam headband really keeps the sweat from dripping down and unlike most of the hats I used to wear, the Tula keeps my head cool, even on the hottest days.
At first, due to the wide brim, I was concerned about windy days but its never popped off once. Its even rather stylish looking. For comfort, sun protection and product quality you couldn't do better.
