Key Takeaways
-
UPF swimwear provides consistent, reliable sun protection that doesn’t wash off or degrade in water like SPF sunscreen does.
-
SPF still plays a role but should be seen as a secondary measure to cover exposed areas, not a primary solution for full-body coverage.
-
Children’s skin is more vulnerable to UV damage, making long-lasting, high-coverage protection like UPF swimwear a smart, proactive choice for every swim day.
Understanding SPF and UPF: What's the Difference, Really?
When it comes to protecting your children from the sun, most parents reach for sunscreen without thinking twice. But what if there's a more reliable, longer-lasting solution—especially for active kids who spend hours in the water? Enter UPF.
SPF, or Sun Protection Factor, is a measure of how long a sunscreen will protect the skin from UVB rays, the kind that cause sunburn. UPF, or Ultraviolet Protection Factor, refers to the amount of UV radiation that can penetrate a fabric and reach the skin. While SPF is applied to the skin and can wear off, UPF is built into the clothing itself and provides continuous coverage as long as it's worn properly.
For example, an SPF 30 sunscreen blocks about 97% of UVB rays if applied correctly and reapplied frequently. A UPF 30 garment, by comparison, blocks about 97% of both UVA and UVB rays all day long, with no reapplication needed.
Why UPF Clothing Offers More Reliable Protection in the Water
Children are constantly in motion—running, swimming, toweling off, and repeating the cycle again and again. Sunscreen, no matter how water-resistant, just can’t keep up. UPF swimwear eliminates many of the common pitfalls of sun protection:
-
No reapplication needed every 80 minutes
-
No missed spots
-
No stinging eyes from sunscreen runoff
-
No degraded protection due to water or sweat
This makes UPF clothing particularly effective for young kids who are less likely to hold still during sunscreen application and more vulnerable to skin damage from prolonged sun exposure.
At Bright & Bold Swimwear, our UPF 30+ garments are designed for long-term sun safety and water durability, helping parents worry less while their kids splash, swim, and play.

SPF Isn’t Designed for Swimwear—Here’s Why That Matters
SPF products are formulated for bare skin, not for fabric or extended water exposure. Here are some of the limitations of relying solely on SPF:
-
SPF must be reapplied every 2 hours—or sooner if swimming
-
Application thickness affects effectiveness
-
Coverage is often inconsistent, especially on fidgety children
-
Sweat and water wash sunscreen away faster than most realize
If sunscreen isn’t applied thickly or evenly, your child may not be receiving the full SPF protection stated on the bottle. Water exposure further reduces SPF’s effectiveness, even with “water-resistant” formulas.
While sunscreen has its place—especially on areas not covered by clothing (like the face, neck, hands, and feet)—it shouldn’t be your only line of defense. UPF swimwear takes the guesswork out of UV protection.
How UPF Swimwear Shields Your Child’s Skin All Day Long
UPF-rated swimwear is engineered to block ultraviolet radiation before it reaches the skin. Here’s how it works:
-
Tight weaves and synthetic fibers like polyester and nylon are used to block UV penetration.
-
Color, thickness, and stretch of the fabric also influence the UPF rating.
-
Built-in UV-blocking technology doesn't wash off or fade quickly like SPF products.
Bright & Bold Swimwear’s high-visibility swimsuits come with UPF 30+ built in—meaning only 1/30th of the sun’s rays can penetrate the fabric. This consistent protection is especially important for children, who have more sensitive skin and spend more time in reflective water environments where UV exposure is intensified.
UPF swimwear is also breathable, lightweight, and quick-drying—ideal for busy, splash-filled days.
The Risks of Relying Only on Sunscreen for Water Activities
Sunscreen is often marketed as a foolproof solution, but it’s anything but—especially around water. Consider these common issues:
-
Missed spots like under the arms, behind knees, or around straps
-
Uneven application from wiggly or impatient kids
-
Rubbing off due to sand, towels, and clothing friction
-
Not enough time between application and swimming
According to dermatologists, most people apply only 25–50% of the recommended amount of sunscreen. That means SPF 50 could be functioning more like SPF 15.
Combine that with a child splashing through chlorinated pools or rolling in beach sand, and your carefully-applied sunscreen might not be offering the protection you think it is.
UPF clothing eliminates these risks entirely in the areas it covers.
Beyond Sunburn: How UV Exposure Affects Children in Water
While sunburn is the most visible sign of UV damage, it’s not the only one. Children are particularly vulnerable to UV exposure for several reasons:
-
Their skin is thinner and more sensitive
-
They accumulate UV damage over their lifetime
-
They spend more time outdoors than adults
Exposure to UV rays increases the risk of:
-
Skin cancer (including melanoma)
-
Premature aging
-
Eye damage (especially without sunglasses or hats)
Water intensifies UV radiation due to reflection, increasing exposure on sunny days. Choosing UPF swimwear is one of the simplest, most effective ways to mitigate long-term risks.
Conclusion
For parents and caregivers, sun safety can feel like a full-time job—especially during summer swim days. But by choosing high-quality UPF swimwear, you're making a confident, parent-approved decision that simplifies sun protection and maximizes safety.
Bright & Bold Swimwear was created with your child's well-being in mind. Our neon-colored, UPF 30+ suits don’t just look good—they help you see your kids clearly in the water and keep them protected from harmful UV rays.

Frequently Asked Questions (FAQs)
What is the difference between SPF and UPF?
SPF measures sunscreen’s ability to protect skin from UVB rays. UPF measures how much UV radiation penetrates a fabric, offering UVA and UVB protection.
Why is UPF better than SPF for swimwear?
UPF is built into clothing, offering consistent coverage and protection without the need for reapplication. SPF wears off, especially in water.
Can I just use sunscreen (SPF) instead of UPF clothing for my child?
Sunscreen is important but less reliable in water. UPF clothing ensures steady, all-day protection in key areas, reducing the risk of missed spots and UV exposure.
How does UPF swimwear protect against sun damage?
It uses tightly woven, UV-resistant fabrics that block harmful rays from reaching the skin, much like sunscreen—but without needing reapplication.
Is UPF swimwear enough, or should I still use sunscreen?
Use both. UPF clothing protects covered areas. Use SPF sunscreen on exposed skin like the face, neck, hands, and feet.
How long does sunscreen last when kids are in the water?
Typically, 40 to 80 minutes depending on the formula. After that, it needs to be reapplied—something easily forgotten during busy swim days.
Does UPF protection wash out or fade over time?
Quality UPF garments maintain their protection over time. However, regular wear and tear can reduce effectiveness. Replace suits every season or if worn frequently.
What UPF rating is best for children’s swimwear?
Look for UPF 30 or higher. UPF 30 blocks 97% of UV rays, while UPF 50 blocks 98%+. Bright & Bold Swimwear offers UPF 30+ as the standard.
Can I trust UPF labels on swimsuits? What should I look for?
Yes, if purchased from reputable brands. Look for products labeled with certified UPF testing and manufactured for UV protection.
Is UPF clothing safe and comfortable for young children?
Absolutely. Our suits are breathable, stretchable, quick-drying, and made for comfort. Kids won’t even notice they’re wearing sun protection.
Are there any downsides to using UPF swimwear?
Some low-quality UPF clothing may lose effectiveness after repeated washes. Always invest in well-reviewed, tested swimwear.
How does UPF clothing compare to reapplying sunscreen throughout the day?
UPF clothing maintains consistent coverage with no need to reapply, unlike sunscreen which must be applied every 2 hours—more often with water exposure.
