Rash Guard Buying Guide

What is a Rash Guard?

Often called a swim shirt, a rash guard is a multi-purpose shirt that was created to be worn for in-water activities. The term rash guard was derived from surfers that first used them to protect themselves from a rash that could be brought on by the board and friction.

Today a rash guard is created for many uses. Kids often use on to stop their arms and chest from getting sunburned while beachgoers and swimmers will also use them for UV protection. And, instead of a wet suit, snorkelers and divers use a rash guard in warm water.

Why Is It Important to Wear a Rash Guard?

Protecting your skin from exposure to the sun and chaffing, a rash guard can be made with any fabric. Typically, a rash guard will be designed like a shirt with some designs available as shorts. Made with fabrics like nylon polyester, and spandex, rash guards are usually lightweight and can be worn under a wet suit.

During warm weather, a rash guard can be worn instead of a wet suit. In colder conditions, you can wear one under a wetsuit to stay warm. Plus, they can protect you from harmful UV rays.

Choosing the Best Rash Guards

Types of Rash Guards

Thermal Rash Guards

Ideal for added warmth when you are in cold water, thermal rash guards are a good choice when you will be in cold water for long periods of time. Typically used for ocean sports or aqua aerobics, a thermal rash guard is made with insulated fabrics to provide warmth. The thickness of the rash guard is measured in millimeters where the higher the number, the warmer it is.

Surf Shirts

A surf shirt is mostly used to protect your skin from the sun. unlike a rash guard, a surf shirt is lightweight and loose-fitting. Too loose to be used for surfing, surf shirts are typically worn like a regular shirt.

Rash Guard Vest

A rash guard vest is a good choice for added warmth when participating in ocean sports. Either used under a wetsuit or by itself, a rash guard vest provides flexibility and maneuverability, which can be helpful in any type of athletic activity. A rash guard vest gives your core an extra layer of warmth, however, it won’t be warm enough to use in cold water activities.

Full-body Rash Guard

A full-body rash guard has the same fit and is made out of similar materials as a typical rash guard, but with a full-body wetsuit design. Used for many types of ocean sports, a full-body rash guard can be worn under a wetsuit or alone. Full-body rash guards are commonly used for surfing, kite surfing, windsurfing, water skiing, wakeboarding, kayaking, and canoeing. 

Things to Consider

Sun Protection

Rash guards are also a good choice if you just want general sun protection. Depending on the UPF level, they can provide coverage for anyone that doesn’t want too much sun exposure. Since they are lightweight and come in both long and short sleeves, you can easily find one that is comfortable and will offer you the protection you need while hanging out on the beach or are doing any outdoor activity or sport.

Size

Available in different sizes, a rash guard is like typical clothing. But, you really want your rash guard choice to be based on your planned activities. 

If you are going to be doing intense activities or competitions like kayaking, swimming, and surfing, you want to choose a rash guard that has a tight fit. You don’t want something that will fly around your body, which will increase your possibility of chafing and decrease hydrodynamics.

Build Materials

Made out of neoprene, nylon, spandex, or polyester, a rash guard can also be a combination of any of the four. Typically, a rash guard is airy and lightweight, which makes them very comfortable. 

UPF
