The New Era 39THIRTY is a premier stretch-fit flexfit style. The shape and fabrics are engineered specifically for the 39THIRTY in order to provide the ultimate stretch fit cap. 39THIRTY was one of New Era’s first departures from the styling of the 59FIFTY. 39THIRTY flexfit caps still have structured crowns and a closed back, but with a pre-curved visor and an interior sweat band made of elastic spandex to fit multiple head sizes. We’ve found the New Era 39THIRTY hats to be comparable with Flexfit hats in quality and construction of the elastic band. Durable, these caps retain their elasticity well, feeling snug but not overly tight for the size range. This is also a low profile, low crown hat. This cap comes in three sizes.
