Designed specifically for children's outdoor travel and based on all-round sun protection and multi-dimensional weight reduction, Kocotree summer hat is a lightweight large-brimmed sun hat with professional sun protection and comfort. It uses a light-filtering sunscreen fabric that effectively blocks 99.9% of UV rays, weighing only 95g. The ergonomic front hat brim, neck-shoulder-integrated large brim, and visor cap design provide all-round sun protection with comfort and breathability. The safety cord has an intelligent lock release buckle to protect the user from strangulation.
