Baseball Cap Style Guide:
This is the Official on field cap for MLB and Minor League teams. Until recently the 59fifty caps were made of 100% wool and had a white sweatband and grey under the bill of the hat.
In 2007 New Era redesigned and replaced the wool with 100% performance polyester. The hats became lighter and more durable. The players said the cap was lighter and liked that the black under the bill of the hat reduced glare.
This is a Fitted Baseball cap, with a lower profile then the 59Fifty. The 49Fourty has a more casual look. The 49Fourty hat is used by a few collegiate teams and is made from the same high quality wool and stitches. The 49fourty hat has a more comfortable fit for that casual college look.
The 39THIRTY is the true fans hat. With its stretch-comfort fit, the 39THIRTY comes in either a performance mesh fabric or a wool-stretch material fitting anyone or any lifestyle. The 39thirty cap is used by the MLB as the official hat of batting practice.
Relax in the New Era unstructured, 29TWENTY cap. Its adjustable fit and simple design makes this the perfect cap for anyone on the go.
