The 8 Best Rash Guards of 2025, According to a Surf Instructor

Wearing a rash guard while you enjoy the outdoors can help keep you safe from the sun’s harmful ultraviolet (UV) rays. The best rash guards are comfortable, quick-drying, and versatile. Most styles have a built-in UV shield, which is crucial when the UV factors are high, says surf coach Thomas Cravarezza.

To find the best rash guards, we spoke with Cravarezza to learn which key features every style should have. Then, we extensively researched dozens of top options from popular brands at different price points. We chose our top picks for their superior fit, comfort, design, and value.

What to Look for When Shopping for Rash Guards

Color: It's not just a matter of personal preference. Dark and bright colors (like yellow, pink, and red) absorb ultraviolet rays more effectively than paler colors do. Also, consider the climate: A darker rash guard will keep you warmer, while white and other light colors will cool you down, says Cravarezza.
Coverage: Check the rash guard's label to find its UPF rating (this indicates how well the rash guard blocks UV rays). The higher the number, the better—UPF50 fabric blocks 98% of the sun's rays.
Sizing: Your rash guard shouldn't be skin tight. Instead, look for one that's a little loose—not so loose that it comes off in the ocean, but not so tight that it pulls as you move your body. Fabric that's stretched too tightly will lose its UV effectiveness over time.
Materials: Nylon and polyester offer the best UV protection. Also, make sure your rash guard has a tight weave, which makes it harder for UV rays to pass through the fabric.
Thermal Protection: For colder climates, consider a rash guard with built-in thermal protection. The extra layer can make a huge difference in cooler temperatures.
Sleeve Length: Long sleeves can help protect your arms from the sun’s UV rays, but short sleeves may feel more breathable and comfortable.

How We Selected the Rash Guards

To choose the best rash guards, we extensively researched dozens of options from popular, trusted brands. We also consulted with a surf instructor to learn which key features every rash guard should have. Then, we reviewed key specs from manufacturers and sorted through customer feedback for dozens of rash guards at a variety of price points to find the top styles. When selecting rash guards, we evaluate each one based on the following key criteria.

Fit: We consider the rash guard's silhouette and customer feedback when assessing how it will fit. Is it made from stretchy, breathable materials? How do wearers feel about the fit? This research helps us determine if the rash guard runs small, large, or true to size.
Comfort: We prioritize rash guards made from high-performance fabrics that won't irritate your skin. We also take into account the rash guard's design—is it adjustable? Does it provide enough coverage?
Design: There are many styles of rash guards available. We evaluate design based on sleeve length, coverage, zippers or fasteners, and color.
Value: To assess a rash guard's value, we weigh its price against its features. Based on its fit, comfort, and design, do we think it's priced fairly? Would we buy it ourselves, or would we only purchase it if it went on sale? How does the price compare to other rash guards on the market?

Our Experts

We consulted our expert at each stage of our research, selecting, and reporting process. Our expert taught us what to look for while shopping for quality rash guards and helped us understand how they can protect the skin from UV rays. Although we choose products independently, expert input influences our decisions.

Frequently Asked Questions

Do rash guards keep you warm?

Some rash guards come with built-in thermal protection or fleece linings that can help keep you warm. But it's worth noting that rash guards are made to block, reflect, and absorb the sun’s rays—not for body temperature control. If you’re looking for something to keep you warm for long periods of time, consider a wetsuit, which is specifically designed to be worn in cold water.

What is the difference between a rash guard and a sun guard?

Rash guards often have a tighter and more compressive fit than sun guards, making them ideal for water sports and outdoor workouts where you want your clothing to stay put. Sun guards, or sun shirts, are often looser and are better equipped for general sun protection while spending time outdoors, but aren't necessarily the best option for intense workouts or water-related activities.

Should rash guards be tight or loose?

Rash guards should feel snug, but not uncomfortably tight. Some even offer compressive fits for additional support during more intensive water sports and workouts. If your rash guard is too loose, it may ride up or shift around, distracting you while you surf or workout.
