When wearing a baseball jersey, it is important to wear something underneath to maintain hygiene. This is because baseball jerseys are often made of a material that can trap sweat and bacteria, which can lead to skin problems and infections. Wearing a base layer under your jersey can help to wick away sweat and keep your skin dry, which can help to prevent these problems. 

Sun Protection 

A t-shirt under a baseball jersey will provide some sun protection, but it is important to note that the SPF of a t-shirt is typically very low. In general, a t-shirt will have an SPF of around 15, which is not enough to protect you from the sun’s harmful UV rays. If you are going to be playing baseball or spending time outdoors in the sun, it is important to wear sunscreen with an SPF of 30 or higher, even if you are wearing a t-shirt under your baseball jersey.


If you are concerned about your modesty, you may want to wear something under your jersey. This will help to cover your chest and shoulders and prevent your jersey from riding up and exposing your skin. It is also important to consider the weather conditions when making this decision. If it is cold outside, you may want to wear a long-sleeved shirt under your jersey to keep warm. If it is hot outside, you may want to wear a tank top or undershirt to stay cool.
