Sun worshippers beware-the Sun Guardian Hat has arrived Made from 100% natural straw, this classic lifeguard hat has been given a serious upgrade: a Upf 50+ brim and top-of-crown liner, an elasticized sweatband for a custom fit, a dark underbrim to reduce glare, an adjustable and technical chinstrap for when the wind picks up, and custom artwork by Carlos del Rio on the crown patch for a special touch. Ideal for outdoor enthusiasts who work and play in full sun.
