7 Best Rash Guards and Swim Shirts for Women

Ready to conquer the water? Here is a breakdown of our favorite rash guards and swim shirts for women. 

Swim shirts or rash guards are an excellent way to block the sun and increase body coverage when you are out in the water.

While there are plenty of awesome waterproof sunscreens and sunblocks, the best way to truly limit your exposure to the sun, and forego the constant reapplication and stickiness that comes with sunscreens, is to wear a swim shirt or rash guard.

Whether you are swimming laps at the local outdoor pool, hitting the beach, or just splashing around in the water, a swim shirt can protect your screen without weighing you down like a traditional short or long-sleeved shirt will.

Made with quick-drying materials, whether it’s polyester, Spandex, or thicker and cold-water-busting neoprene, rash guards are designed to protect you from the elements while keeping you comfortable.

Here is a breakdown of our hand-picked favorites of the best swim shirts and rash guards for women.

Rash Guards for Women – What You Need to Know

Women’s rash guards come in a large range of sizes, materials, thicknesses, colors, and of course, price.

While rash guards are primarily used for ocean activities like surfing, they are an excellent multi-purpose swim shirt that can be used for a wide range of activities.

Here’s a look at the information you need to make the right choice in picking the rash guard that matches your needs and goals in the water.

Let’s go!

What is the purpose of a rash guard?

Rash guards are designed to protect your skin from the sun, keep you warm in cold water, and protect your skin from rashes and the elements.

Swim shirts can be used for swimming in outdoor pools and for warmer open water swims to limit sun exposure.

Rash guards are a way to provide more modest coverage when at the pool and the beach.

Women’s rash guards are designed to be comfortable, dry quickly after being in the water, and stretchy to be snug on the skin.

Rash guards give excellent sun protection and are available in a wide range of shapes and sizes to match every kind of activity and sport.

What are rash guards made of?

Women’s rash guards are typically made of neoprene, polyester, nylon and elastane (or one of elastane’s branded versions, including Lycra and Spandex).

Here is a quick look at the materials and their respective benefits:

  • Elastane (also known as Lycra and Spandex). Elastane is a synthetic material that is known for its stretchiness and water-repellence. Although this fabric is comfy and helps provide a superior and custom fit, it does degrade when repeatedly exposed to harsh pool chemicals like chlorine.
  • Neoprene. This material is one of the most popular for open water and cold water swimming shirts and suits (and wetsuits, too!). Neoprene is perfect for swimmers who are going to be in really cold water. It retains heat and is soft on the skin. Neoprene is especially susceptible to pool chemicals, so avoid wearing neoprene rash guards in the pool if possible.
  • Polyester. Polyester is the King Daddy of swimming fabrics. It lasts almost forever, holds color, doesn’t stretch, and stands up spectacularly to chlorine and bromine. While polyester rash guards are awesome for comfort and durability, they don’t have a lot of stretch or insulation.
  • Nylon (or polyamide). Nylon is another synthetic fabric that is soft on the skin, highly durable, and one of the common materials used in swim shirts for their breathable and form-fitting properties.

Rash guards aren’t made exclusively of these fabrics, with most of them being constructed of a variety of those materials.

Most swimming shirts for women, for example, are made of a blend of polyester or nylon with elastane, a light and flexible combination ideal for swimming. Rash guards, especially those designed for cold water, are built with neoprene.

Ultimately, the fabric(s) in your rash guard should line up with your goals for the shirt and the water.

What are thermal rash guards?

Thermal rash guards, which are designed to provide extra warmth in cool water, are excellent as a form of swimwear for aerobics and provide a balance between swimwear and wetsuits.

Thermal women’s rash guards are built mostly from neoprene and are thicker than regular swim shirts and rash guards. The warmest of these kinds of rash guards are up to 5mm thick.

Long sleeve vs short sleeve rash guards

Whether you choose a short sleeve or long sleeve rash guard is ultimately up to you and your personal preferences.

Long sleeve swim shirts obviously provide more coverage and protection from the sun. Short sleeve rash guards give you more flexibility and range of motion.

Rash guards also come in a tank version, but this is less frequent. Sleeveless rash guards provide maximum flexibility with reduced sun coverage and heat retention.

How fast do rash guards dry?

These kinds of swim shirts are designed to dry quickly. Wearing a wet, soggy shirt between swims and surfs is no one’s idea of a good time. Damp fabrics give you a chill and is uncomfortable.

Fortunately, swim shirts and rash guards are built specifically to dry quickly. Rash guards feature materials that repel water and wick moisture to help you get dry quickly after hopping out of the pool or ocean.

Extra features of rash guards and swim shirts

Swim shirts and rash guards have a variety of extra bells and whistles that can make the most of your time in the water.

For example, additional features include thumb hooks which help keep the shirt from riding up when you swimming, a hood to provide extra sun protection (and heat retention), board connectors, and even small pockets for stashing valuables while in the water.
