UV swimwear uses fabric that has been rated with a UPF (Ultraviolet Protection Factor). A UPF 50 rating, for example, blocks 98% of UVA and UVB rays[1].
The weave tightness, material composition (like nylon, polyester, and elastane), and chemical finishes determine UV blocking efficiency. Dense, dark-colored fabrics offer more protection.
While a standard cotton t-shirt may have a UPF of 5–10, UV-protective clothing is designed to retain its blocking effect even when wet. Learn more from the Skin Cancer Foundation.
Fabric Type | Typical UPF | Sun Protection Level |
---|---|---|
Regular Cotton | 5–10 | Low |
Polyester (Tightly Woven) | 30–50 | High |
UPF Certified Nylon Blend | 50+ | Excellent |
Unlike sunscreen, which wears off and requires reapplication, UV swimwear provides consistent coverage as long as it stays in place.
UPF-rated fabrics retain effectiveness even when wet, whereas sunscreen loses SPF effectiveness due to water and sweat[2].
Experts recommend wearing UV swimwear and applying sunscreen on exposed areas for full-body protection. Read more at American Cancer Society.
Protection Method | Consistency | Needs Reapplication? | Best Use |
---|---|---|---|
UV Swimwear | Stable | No | Water activities |
Sunscreen (SPF 30+) | Varies | Every 2 hrs | Exposed skin |
Combination | High | Yes (for SPF) | All-day outdoor protection |
Look for swimwear labeled UPF 50+, which is the highest rating recognized by testing standards like AITEX or ASTM D6603.
Stretchy, dense, and quick-dry fabrics like Lycra and high-performance polyester blends tend to offer the best UV resistance. A snug fit prevents gaps in protection.
Long sleeves, high necklines, and rash guard styles offer the most coverage. Brighter colors may also reflect more sunlight than dark hues.
