This Reima Biitsi sun protection hat brings UPF 50+ coverage in breathable, recycled 100% polyester fabric to keep kids safe during sunny outdoor play. This sun cap features a wide visor and an extended back brim (neck flap) to shield the face and neck for longer, more comfortable playtime. This lightweight, durable design has no lining for a cool feel and is ideal for beach days, playgrounds, and all-day outdoor adventures. UPF 50+ is tested to EN 13758-1 +A1, but protection can decrease when the fabric is wet, stretched, or worn over time, so pair with sunglasses and sunscreen to protect exposed skin.
