What is the difference between the different types of baseball jerseys?

The jersey, a knitted garment distinctively worn by players or fans, is the most important piece to a baseball uniform. A baseball jersey often includes the competitor’s team logo, name, and number stitched in a team colored theme. Baseball teams have several versions of jerseys for home, away, and alternate conditions. At Rally House, we want to provide buyers and collectors the information needed to support their baseball jersey purchasing decision. Each type of jersey should be carefully considered before purchasing.

Types of Baseball Jerseys:

Baseball jerseys come in a variety of styles. Each type features different variations in cost, style and material.

Authentic Jerseys:

Majestic is the manufacturer of authentic Major League Baseball (MLB) jerseys. These baseball jerseys include all of the same features worn by the elite, on-field players. Sizing is numerical; 40 = Small, 44 = Medium, 48 = Large, 52 = X-Large, 56 = XX-Large and 60 = XXX-Large. Authentic jerseys are officially licensed by MLB and include a sewn-in MLB logo just below the neckline on the back. Additionally, these jerseys feature anywhere from one to four of sewn-on patching and lettering made of very durable double-knit polyester fabric. Featuring Cool Base technology, the moisture wicking performance mesh provides temperature control to keep the wearer cool and comfortable.

Replica Jerseys:

Replica jerseys are the cost effective version of the Authentic, and yet still officially licensed by MLB. Featuring a mesh fabric, Replica jerseys present a style that mimics the look and feel of the on-field design. The lettering and numbering are made from a plastic, imitative, tackle-twill and come ironed-on or single stitched. These jerseys do not have the sewn-in MLB logo below the neckline; the logo is ironed-on or single stitched.

Custom Jerseys:

A relatively new service, customized jerseys, allows fans to personalize their favorite team jersey. We customize each jersey to individual team specifications in regards to size, color and font style. Using Cool Base fabric, printed twill letters and numbers are heat pressed on to give the effect of a multilayer, multicolor application. Visit one of our in-store digital kiosks or create online to build your own personalized jersey.

Alternate Jerseys:

Alternate jerseys offer a distinguished look for teams playing with similar colors. Often called third jerseys, the Alternates are styled after vintage throwback uniforms or single game commemoratives.


There is no better way to express your love for the game than with a Cooperstown jersey. Cooperstown jerseys are the classic team and player jerseys reproduced with modern fabric to achieve a fresh fit. Created by Mitchell & Ness, Cooperstown jerseys feature a ‘throwback’ design and commemorative patch for players exclusively in the Hall of Fame.

Batting Practice:

Batting Practice jerseys are the on-field jerseys worn by players during spring training and warm-ups. Officially licensed by MLB, these jerseys feature tackle-twill team logos and lettering. Made with Cool Base performance technology, the stretch mesh fabric provides enhanced range of motion and added comfort.
