Sunday Afternoon Ultra Adventure HatA full brim and a full view! Sun protection is great, but it can sometimes block peripheral vision. Weve 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 underbrim reduces glare. Tennis court? Garden? Canoe trip? Yes!
