A full brim and a full view! Sun protection is great, but it can sometimes block peripheral vision. Sunday Afternoon's engineered the Sport Hat to keep your perspective wide open in three ways: 1. Streamlined hat design keeps vision clear. 2. Ventilation and wicking sweatband keep you cool and your eyes on the prize. 3. Dark under-brim reduces glare. Tennis court? Garden? Canoe trip? Yes!
