Why you should wear rash guards when scuba diving

When it comes to scuba diving, safety should always be the top priority. There are many safety measures that divers can take to minimize the risks associated with diving. Wearing a rash guard is one of them. In this article, we will discuss the reasons why you should wear a rash guard when scuba diving and how it can benefit you.

Our rashguards, or swim shirts, are made of very stretchy spandex and polyester, which allows for breathability. They are quick drying and made for water activities. In warm waters, scuba divers can wear the rashguard alone. It also fills a purpose under a wetsuit as it makes the “donning” and “doffing” easy. The UPF 50+ sun protection blocks 98% of harmful rays.

What is a rash guard?

A rash guard is a type of athletic shirt that is made of a material that is designed to protect your skin from the sun and other environmental hazards. Rash guards are typically made of materials such as spandex, nylon, or polyester. These materials are quick-drying and offer protection against UV rays.

Why wear a rash guard when scuba diving?

  1. Protects your skin from the sun

When scuba diving, you are exposed to the sun for extended periods of time, which can lead to sunburns and long-term skin damage. Rash guards provide a barrier between your skin and the sun, reducing your risk of sunburn and skin damage.

  1. Protects your skin from marine life

When diving, you are often in close proximity to marine life, some of which can be dangerous. Jellyfish, sea lice, and other creatures can cause skin irritations, rashes, and even stings. Rash guards can protect your skin from these creatures and prevent painful stings or irritations.

  1. Provides thermal protection

In addition to protecting your skin from the sun and marine life, rash guards can also provide thermal protection. When diving in cold water, a rash guard can help regulate your body temperature and prevent hypothermia.

  1. Prevents chafing

Wetsuits can sometimes cause chafing and irritation, especially if they do not fit properly. A rash guard can be worn underneath a wetsuit to reduce friction and prevent chafing.

  1. Easy to clean and maintain

Rash guards are easy to clean and maintain, which is important for scuba divers who want to keep their gear in top condition. They can be washed in a washing machine and hung up to dry quickly.


Wearing a rash guard when scuba diving is a simple and effective way to protect your skin from the sun, marine life, and cold water, as well as prevent chafing. It is a small investment that can pay off in big ways when it comes to your safety and comfort while diving.
