Benefits of rash guards

Our high-quality rash guards offer the following benefits:

  1. Abrasion and irritation protection
  2. Performance enhancement
  3. Extra warmth
  4. Durability 
  5. Compression
  6. Style expression
  7. UV protection

Abrasion and irritation protection

Our rash guards prevent abrasion, chafing, and skin irritation. The smooth fabric layers serve as a barrier between bare skin and sand, activity gear, boards, or playing surfaces. This helps prevent painful rashes, harness chafe, and turf burns.

Performance enhancement

The flexible, stretch fit of our rash guards improves range of motion and boosts athletic performance. Compression increases blood flow and oxygen, while breathability regulates body temperature. Rash guards allow outdoor athletes to remain comfortable, focused, and sun safe.

Extra warmth

The tight compression fit of our rash guards provides the body with additional warmth in cool water. By trapping a thin layer of water between the skin and fabric, rash guards help maintain body temperature during water activities. 

The quick-drying material also limits heat loss once out of cold water by preventing a breeze directly on the skin. Our rash guards offer extra warmth when enjoying the water.


With reinforced stitching and durable technical fabric, our rash guards are designed to hold up through repeated use. They maintain their structural integrity after exposure to salt water, chlorine, and abrasion. Your rash guard will last for years and maintain its quality.


The form-fitting cut of our rash guards provides beneficial compression to the muscles. This can boost circulation while also reducing the onset of fatigue. The flexible second skin fit allows unrestricted mobility for paddling, swinging, and reaching movements.

Style expression

With so many different colors, prints, and designs, our rash guards allow you to showcase your style. Mix and match solid colors and patterns to create a customized watersports look. Or coordinate with our collection of board shorts, bikinis, or wetsuits for a trendy, stylish finish.

UV protection

Our rash guards offer excellent UV protection. The fabric we use is rated UPF 50+ for the highest level of sun protection, blocking 98% of UVA and UVB rays.

This helps protect the skin from harmful sun rays and keeps you protected for hours of fun in the sun.

Factors to consider when choosing a rash guard

With so many rash guard options, it can be tough to choose the right one. Here are some tips you can follow:

  • UV protection. This should be your top priority. All our swimwear comes with a high UPF rating, which indicates how effectively the fabric blocks harmful UV rays. Also, consider the fabric construction and composition, as tightly woven, lightweight materials tend to offer superior sun safety.
  • Fit and comfort. A proper fit is crucial for both sun protection and unrestricted movement in the water. Opt for rash guards made from stretchy, flexible materials that move with your body. Flat seams and a chafe-free design will also improve comfort for all day wear during extended wear.
  • Durability and quick-drying. Invest in long-lasting, high-quality materials to ensure your rash guard withstands frequent use and exposure to the sun, salt water, and chlorine. Look for fabrics with quick-drying properties to prevent the garment from becoming waterlogged and heavy.
  • Style and design. While function should be the primary concern, rash guards are available in a variety of colors and patterns to suit your style. Consider whether you prefer full coverage with long sleeves or more breathability with short sleeves. Zip-up designs offer added convenience, while pull-over styles provide a streamlined look.

Rash guards FAQ

Do you wear anything under the rash guard?

Women often wear a bathing suit top or a swim bra under a rash guard for additional support and coverage, as rash guards can be thin and sheer, especially when wet. It’s really a matter of personal preference.

Men usually don’t wear anything under a rash guard. They typically wear them with board shorts or swim trunks.

Is a rash vest the same as a rash guard?

A rash vest is the same as a rash guard. These terms are often used interchangeably to describe a type of athletic shirt made of spandex, nylon, or polyester that is worn in water sports to protect against sunburn, chafing, rashes, and long-term skin damage caused by abrasion

Do you wear a rash guard over your swimsuit?

Rash guards can be worn as a stand-alone swim top, or over a bikini top or one-piece swimsuit. They provide an additional layer of protection from the sun's harmful UV rays. They also protect against chafing caused by surfboards, wetsuits, or other water sports equipment.

Do you wear a bra with a rash guard?

Women often wear a bra or a swim top under a rash guard for breast support and coverage. Regular bras are not recommended for use under rash guards due to potential damage from the pool or salt water. Instead, swim bras, bikini tops, or sports bras made from quick-drying fabrics are suitable choices.

What is the best material for rash guards?

The best materials for rash guards are lightweight, quick-drying synthetic fabrics such as our nylon and spandex blend. These materials have great moisture-wicking properties, stretchy flexibility, and the ability to provide sun protection through tight weaves or specialized coatings.

Is a rash guard just a compression shirt?

While rash guards and compression shirts share some similarities in their form-fitting design, they serve different purposes. Rash guards are specifically engineered for water sports, offering sun protection, moisture-wicking, and abrasion resistance, while compression shirts are primarily designed for improved muscle support and circulation during intense physical activities.

Why do surfers wear long sleeves?

Surfers wear long sleeves for protection against the sun's harmful UV rays and to prevent skin abrasion from contact with the surfboard, surf wax, or sand. Long sleeves also offer additional warmth in cooler water temperatures and can protect against jellyfish stings or other irritants in the water.

Should a rash guard be tight or loose?

A tighter-fitting rash guard is better for high-performance activities such as surfing and paddle boarding, where less drag is desired. A looser-fitting rash guard might be more suitable for relaxed activities or when floating and lounging. The fit should allow for comfort and a full range of motion.

Do I really need a rash guard?

While not strictly necessary for all water activities, rash guards offer several benefits that make them highly recommended, especially for extended periods of time in the sun or for water sports involving potential abrasion. 

They provide excellent sun protection, prevent chafing and rashes, offer warmth in cooler waters, and can enhance performance by reducing drag. For these reasons, many water enthusiasts consider rash guards an essential piece of gear.
