Understanding the Importance of Sun Protection While Swimming
How UV Rays Affect Your Skin During Water Activities
Water activities intensify UV exposure by 50% through reflection, making swimmers particularly vulnerable to skin damage. The cooling effect of water masks sunburn development, often leading to severe burns before you notice symptoms. UVA rays penetrate deep into skin layers causing premature aging, while UVB rays damage surface skin cells and directly contribute to skin cancer risk.
The Difference Between UPF and SPF Ratings
UPF (Ultraviolet Protection Factor) measures fabric’s ability to block UV radiation, while SPF (Sun Protection Factor) rates sunscreen effectiveness. A UPF 50 swim shirt blocks 98% of all UV rays, providing consistent protection that doesn’t wash off. Unlike sunscreen’s SPF rating which primarily measures UVB protection, UPF measures protection against both UVA and UVB rays.
What to Look for When Buying a Sun-Protective Swim Shirt
UPF Rating Requirements
The UPF (Ultraviolet Protection Factor) rating is the single most critical feature to consider when selecting a sun-protective swim shirt. Always look for shirts with a UPF 50+ rating, which blocks 98% of both UVA and UVB rays. This highest possible rating is specifically recommended by The Skin Cancer Foundation for maximum protection during water activities, ensuring your skin stays safe even during extended outdoor exposure.
Material and Comfort Considerations
Choose swim shirts made from lightweight, breathable, and quick-drying fabrics that won’t weigh you down in water. Top brands like Coolibar and Shark Zen offer UPF 50+ materials that are both protective and comfortable. The best swim shirts feature moisture-wicking properties that prevent the fabric from becoming heavy when wet, enhancing your overall comfort and allowing for better performance during swimming, paddling, or surfing.
Fit and Coverage Options
Select a swim shirt with a body-skimming fit that won’t balloon underwater while still allowing full range of motion. For maximum sun protection, long-sleeve options significantly reduce the need for sunscreen reapplication, though short-sleeve versions are available for warmer conditions. Consider specialty features like hoods (found in the REI Co-op Sahara Shade Hoodie) for additional neck and scalp protection, especially during activities with prolonged sun exposure like kayaking or snorkeling.

Washing Tips to Maintain UPF Rating
Always wash your sun protection swim shirt in cold water with mild detergent to preserve the UPF coating. Avoid bleach and fabric softeners as they can degrade the protective properties. Skip the dryer—instead, line dry your shirt in the shade or use the lowest heat setting if machine drying is necessary. Manufacturers like UV Skinz and Coolibar recommend washing after each use to remove salt, chlorine, and oils that can damage UPF fabrics.
Extending the Lifespan of Your Swim Shirt
Store your swim shirt away from direct sunlight when not in use to prevent UV damage to the protective fabric. Rinse thoroughly with fresh water immediately after swimming in chlorinated pools or salt water. Avoid rough surfaces that can cause abrasion and wear down the UPF treatment. Follow brand-specific care instructions—REI Co-op and Title Nine provide detailed guidelines for their UPF 50+ products. Replace your swim shirt when it becomes visibly stretched, thin, or discolored, as these are signs the sun protection may be compromised.

Frequently Asked Questions
What is a swim shirt and why should I use one?
A swim shirt (or rash guard) is a protective garment designed for water activities that shields your skin from harmful UV rays. Unlike regular sunscreen that needs reapplication, swim shirts provide constant sun protection, especially valuable since water activities can increase UV exposure by 50% due to reflection. They’re ideal for beach outings, pool parties, and water sports, combining convenience with effective protection.
What’s the difference between UPF and SPF?
UPF (Ultraviolet Protection Factor) measures a fabric’s ability to block UV radiation, while SPF (Sun Protection Factor) rates sunscreen effectiveness. A UPF 50 swim shirt blocks 98% of UV rays and provides consistent protection that doesn’t wash off in water. Sunscreen with SPF rating requires regular reapplication, especially after swimming, making UPF clothing a more reliable option for extended water activities.
What should I look for when buying a sun-protective swim shirt?
Choose swim shirts with UPF 50+ rating (recommended by The Skin Cancer Foundation), lightweight and quick-drying fabrics for comfort, and appropriate fit and coverage. Long-sleeve designs provide maximum protection, though short-sleeve options are available. Consider additional features like hoods for extended sun exposure. Brands like Coolibar and Shark Zen are known for quality sun protective swimwear.
How do I know if a swim shirt fits properly?
A proper-fitting swim shirt should be body-skimming but not restrictive. It should allow full range of motion while swimming or engaging in water activities. The shirt shouldn’t ride up when you raise your arms, and sleeves should reach your wrists (for long-sleeve models). Ensure there are no uncomfortable seams that might cause chafing when wet.
Are there swim shirts for different body types?
Yes, many brands offer size-inclusive options for all body types. Companies like UV Skinz and Coolibar provide extended sizing ranges with designs that flatter different body shapes. Some brands offer relaxed fits for those preferring looser coverage, while others provide more tailored options. Look for products with detailed sizing guides to find your perfect match.
How can I make my UPF swim shirt last longer?
Maintain your swim shirt’s UPF protection by washing in cold water with mild detergent, avoiding bleach and fabric softeners, and line drying in shade. Always rinse after exposure to chlorine or saltwater. Store away from direct sunlight when not in use. Replace your swim shirt when it shows signs of wear like stretching, fading, or discoloration, as these indicate diminished sun protection.
Are budget-friendly swim shirts effective for sun protection?
Yes, quality sun protection is available at affordable prices. Brands like Baleaf and Shark Zen offer UPF 50 swim shirts under $30 that provide excellent protection. While premium options from REI Co-op and Coolibar may last longer for frequent beachgoers, budget-friendly alternatives still offer the UPF 50+ protection recommended by dermatologists when properly maintained and replaced as needed.
Do children need special swim shirts?
