Which sunscreen hat is better, lemon baby or kk tree?

Kk tree is nice. Kk tree's SPF is above 50, with good air permeability, and lemon baby's SPF is above 30, with poor air permeability, so kk tree is good. Matters needing attention in purchasing sun protection caps. Choosing a wide-brimmed sunscreen hat can provide more comprehensive facial sunscreen protection. The brim should be moderate in length, which can not only block the sun, but also keep comfortable.
