UPF 50+ vs SPF: What Parents Need to Know for Real Sun Protection
If you’re a parent, you already know how tricky “sun protection” can be. You’ve got sunscreen in one hand, a hat in the other, and somehow your child still manages to get a pink nose by afternoon.
To make matters even more confusing, swimwear tags now say UPF 50+, while sunscreen bottles say SPF 30 or SPF 50. They sound similar — but they’re not the same thing. Understanding the difference can make a big difference in how well your kids are protected during all those beach trips, pool afternoons, and backyard playtimes.
SPF vs UPF: What’s What
You’ve probably heard about SPF for years. SPF, or Sun Protection Factor, is what sunscreen uses to measure how long it can protect your skin from UVB rays — the ones that burn. An SPF 30 sunscreen, for example, means you can stay in the sun roughly 30 times longer before burning, assuming you apply enough (and reapply).
UPF, or Ultraviolet Protection Factor, works differently. It’s a rating used for fabric — clothes, swimsuits, even hats — that tells you how much of the sun’s rays can pass through. A UPF 50+ shirt blocks about 98% of UV rays. In other words, only 2% get through.
Think of it this way:
- SPF = for skin (lotion).
- UPF = for clothing (fabric).
And unlike sunscreen, UPF fabric doesn’t wash off or sweat off, and it doesn't need a timer to reapply.
Why Parents Love UPF 50+ Kids Swimwear
Here’s the thing: kids rarely stay still long enough for you to keep up with sunscreen reapplications. That’s why UPF 50+ kids' swimwear is such a game-changer — it offers constant protection without the need to chase anyone down with a bottle of sunscreen.
The moment your child puts it on, they’re covered from the sun’s harsh rays. Those tricky spots that are easy to miss — like shoulders, backs, and upper arms — stay safely shielded.
Because Tuck & Char Co.’s swimwear is made from breathable, stretchy materials, kids can swim, jump, and play freely without feeling restricted.
It’s also perfect for little ones with sensitive skin who find sunscreen stings or feels sticky. With UPF 50+ swimwear, protection is simple, mess-free, and built right into every fun-filled day under the sun.
Choosing the Right Swimwear
When shopping for sun-protective pieces, keep these tips in mind:
1. Check the Label
Always look for the UPF 50+ mark. It’s the highest level of fabric protection you can get.
2. Pick the Right Fabric Coverage
A long-sleeve rash guard or full-body suit may sound like too much, but once they hit the water, it’s surprisingly comfortable — and saves you from missing spots with sunscreen.
3. Lightweight and Quick-Dry
Good UPF swimwear should dry fast and feel cool to the touch, even when wet. Besides, moms want beach clothes to be as lightweight as realistically possible so we can pack more with less luggage.
4. Keep It Fun
Kids are more likely to wear it if it’s colorful or patterned. That’s why Tuck & Char Co.’s signature prints reflect that playfulness and fun, like bright waves, sea animals, and cheerful colors that stand out.
The Best of Both Worlds: UPF + SPF
Even the best swimwear can’t cover everything. You’ll still need sunscreen for exposed areas like faces, feet, and hands. Here’s a quick combo routine:
- Apply SPF 30 or higher sunscreen 15 minutes before heading out.
- Dress kids in UPF 50+ clothing for lasting coverage.
- Reapply sunscreen every couple of hours (especially after swimming or towel-drying).
It’s a simple habit that keeps the fun going and burns away.
