Premium Rash Guards & Swim Shirts: Ultimate Sun & Surf Protection
Whether you’re surfing, swimming laps, snorkeling, or spending a long day at the beach, a rash guard or swim shirt is one of the easiest ways to stay comfortable in the sun and water. Rash guards help reduce chafing from boards, straps, and sand while adding UPF 50+ sun protection for exposed skin. Swim shirts offer similar coverage with a more relaxed feel—great for casual pool days and family trips.

Shop by Activity
Rash Guards for Surfing & Watersports
If you’re in the ocean, prioritize stretch and comfort. Softer, more elastic blends are ideal for paddling and board movement. Look for flatlock seams to reduce rubbing and a secure fit that won’t ride up under a wetsuit or life vest.
Rash Guards for Lap Swimming & Pool Use
For frequent pool sessions, choose fabrics that hold color and shape. Many swimmers prefer more chlorine-friendly materials for repeat exposure—especially if you train several times per week.
Rash Guards for Sun Protection & Beach Days
Planning a long day outdoors? A long sleeve rash guard or swim shirt can help limit reapplication of sunscreen on arms and shoulders. Consider hooded options for extra neck and scalp coverage, and relaxed fits for all-day wear.
Rash Guard vs. Swim Shirt: What’s the Difference?
A rash guard is typically a more fitted performance top designed to move with you in the water—popular for surfing, training, and high-activity use. A swim shirt (often called a sun shirt) usually has a looser, more casual fit for comfort at the pool or beach. If you want flexibility for board sports, choose a fitted rash guard. If you want easy coverage you can throw on over swimwear, a swim shirt is a great pick.

How to Choose the Right UPF Rating
UPF measures how much UV radiation a fabric blocks. UPF 50+ is a common choice for swimmers because it offers high coverage for extended time outdoors. For the best real-world protection, prioritize coverage (long sleeves, higher necklines) and a fit that stays put in the water.
Can you wear a rash guard in a chlorinated pool?
Yes. If you swim frequently, choose materials designed to better handle repeated chlorine exposure and follow care instructions to extend lifespan.
How do I choose between long sleeve and short sleeve?
Long sleeves offer more sun coverage; short sleeves can feel cooler in hot weather. Choose based on sun intensity, activity, and comfort preference.
Should a rash guard fit tight or loose?
A performance rash guard should be snug but comfortable so it won’t ride up. Swim shirts are often looser for all-day comfort.
What does UPF 50+ mean on a rash guard?
UPF 50+ indicates the fabric blocks a high percentage of UV rays. Coverage and fit also matter for effective sun protection.
What is the difference between a rash guard and a swim shirt?
Rash guards are typically fitted for performance and watersports; swim shirts are usually relaxed-fit for casual sun protection and comfort.
