The Little Sol Hat is made of durable Silkweightim fabric with 50+ UPF sun protection and lined with no-itch polyester jersey. Its multipanel construction provides a good fit, and an inner band wicks moisture. The separate front and back brim lend full coverage; front panel can snap up for improved view. Chafe-free chin strap with breakaway clasp closure for safe, secure fit. Made of 83% recycled nylon/17% spandex (prints: 83% recycled polyester/17% nylon).
