What Hats Do MLB Players Wear? A Guide to Pro Baseball Caps and How to Create Your Own

Simply put, Major League Baseball players today wear the 59FIFTY New Era fitted caps as the official on-field cap across all 30 teams and have been the standard and preferred hat of MLB since 1993. These hats feature fitted sizing with no adjustable closure, a structured six-panel crown, thick lining of performance polyester for a secure feel, and team logos embroidered on the front and/or side panels. Players can choose between high-crown and low-profile styles, accommodating different hair types and personal styles. 

However, the 59FIFTY hat was born much earlier. In the 1950’s, Harold Koch created a very carefully woven 100% worsted wool hat that took inspiration from an earlier silhouette called the “Brooklyn Style”, which featured an 8-row stitch on the brim, creating an elevated look that didn’t exist at the time. As time went by, additional stiffening material was added to the back of the crown to make the front logo stay visible while being worn, as designers noticed that with repeated wear, the logo would become barely visible. This small change made the baseball cap something short of a visible and effective marker for team branding for decades to come. 

Who Makes MLB Hats? The Brands Behind Pro Baseball Caps

New Era is the official MLB on-field cap manufacturer and has been since the 1990’s. Of course, they manufacture the 59FIFTY hat itself, but also a series of other versions like the 9FIFTY, 39THIRTY, 9FORTY, 9TWENTY, 29TWENTY, and the 19TWENTY that all share their unique perks for all hat needs. The other major licensed hat manufacturer for the MLB is 47 Brand, which specifically focuses on fan and lifestyle caps that are fully adjustable with relaxed-fit options as well. They even come in a wide range of clubs, from minor league to national to international clubs for every kind of fan imaginable.

Types of MLB Hats and What Makes Each One Different

There are multiple types of hats in the MLB New Era world, but each has its own unique differences and perks to cater to every fan. Here’s the full available range of the New Era MLB Series from start to finish: 

On-field vs Replicas: What’s the difference? 

Players within the MLB and Minor League World exclusively wear the 59FIFTY Fitted Caps as the standard attire. Replicas, however, are made exclusively for fans for casual and functional wear, with the ability to customize and buy precise sizing options online. 

Why Baseball Players Wear Hats (And Why the Fit Matters)

The answer to this is simple: the sun isn’t something you should mess around with, both on the pitch and on your body. Players need full visibility of the ball, whether it’s down below or up in the air, ahead of a home run. So having a good amount of shade over the eyes will help players (and watchers alike) find the ball, without potentially harming or putting strain on their vision.Not to mention it being a tried and true way of offering sun protection on the face. 

But besides the practical aspect, it’s also an opportunity for clubs to showcase who they are. Whether it's showcasing their club colors, sponsors, logo, flag, you name it. The fitted nature of the on-field hats means a secure fit to last the whole game, no pesky hardware between matches, and a clean uniform look for the whole team. It’s part of the reason why fitted and structured baseball caps are the gold standard when it comes to the attire and sport.
