More Than 80% of Melanoma Cases Are Caused by UV Exposure. We’re Here to Change That.

In 2025, a global study confirmed what dermatologists have been saying for years: Over 80% of melanoma cases in 2022 were directly linked to UV radiation.

That's not meant to scare you. It's meant to shift how you think about sun protection.

Most people grab a bottle of SPF before heading outside and figure that covers it. But sunscreen wears off. You sweat through it. You forget to reapply. And that T-shirt you threw on? A standard cotton tee offers a UPF of around 5, meaning roughly 20% of UV radiation still gets through to your skin.

There's a better way to stay covered.

What UPF Actually Means

UPF stands for Ultraviolet Protection Factor. It's the clothing equivalent of SPF, except it's tested against both UVA and UVB rays simultaneously.

A UPF 50+ rating blocks over 98% of UV radiation from reaching your skin. That's not marketing language. It's a measurable, lab-tested standard.

Here's the gap that matters: most everyday fabrics offer little to no meaningful UV protection. A white cotton tee in good condition sits around UPF 5. Worn, stretched, or wet? Lower still.

UPF 50+ apparel closes that gap completely, and it does it without asking you to stop, reapply, or think about it.

Why Sun Protection Has to Work While You Move

If you play pickleball, tennis, golf, or softball, or you hike, run, or spend long stretches outdoors, sunscreen alone isn't a reliable strategy.

The problems are predictable: you sweat, the sunscreen breaks down, you're focused on the game and not watching the clock, and two hours pass faster than you think. By the time you notice, you've already got more exposure than you planned for.

UPF 50+ clothing works differently. It's passive protection. You put it on, and it does the job regardless of how hard you're working, how much you sweat, or how long you're out there.

That's the point. Protection that keeps up with you.

What Makes Sparms Different

Sparms builds UPF 50+ performance wear specifically for people who move. Not beach cover-ups. Not bulky UV shirts you'd wear on a boat. Gear that's built for sport and outdoor activity, and designed to stay out of your way while you compete or train.

Every piece is made with CoolTech FusionFlexXP fabric, engineered for warm conditions and high output:

Certified UPF 50+, lab-tested and verified Cooling performance that helps reduce skin temperature by up to 2°C Breathable and lightweight, so you stop noticing it after the first few minutes Quick-dry and moisture-wicking, built for effort PFAS-free, no harmful chemicals in the construction

The goal is simple: wear it, forget it's there, finish strong.

You Still Need Sun Protection in Spring

A lot of people mentally associate serious UV exposure with midsummer. But UV radiation doesn't wait for July.

In the US, UV index levels start climbing in March and April across most of the country, and by May they're high enough to cause skin damage in as little as 15 minutes for fair-skinned people. Spring sports like pickleball leagues, golf rounds, and softball games often run for hours, right in the middle of peak UV windows.

The timing of when you're outside matters more than the temperature. A cool, partly cloudy spring day can still deliver a high UV index, and cloud cover only blocks a portion of UV rays.

Starting your protection habits in spring, rather than waiting until it "feels hot enough," is one of the simplest changes you can make.

How to Build a Complete Sun Protection Kit

Sparms is your first layer. Here's how to build the rest:

Start with UPF 50+ coverage. Arm sleeves, shoulder wraps, base layers, and leggings cover the highest-exposure areas without restricting your movement.

Apply SPF 30+ sunscreen to any skin that isn't covered. Reapply every two hours, especially after sweating heavily.

Add a wide-brim hat and UV-rated sunglasses. Your face, ears, and eyes are consistently high-exposure zones that clothing often misses.

Be aware of peak UV hours. In most of the US, UV intensity is highest between 10am and 4pm. When you can, schedule long outdoor activities outside that window, or make sure your protection is dialed in before you start.

It doesn't have to be complicated. It just has to be consistent.

The Bottom Line

More than 80% of melanoma cases are preventable. That's the real headline here.

Sun protection that actually works isn't about doing more. It's about making smarter choices at the start, so you're not scrambling to catch up mid-round or mid-match.

Gear up properly. Stay out longer. Don't cut it short because your skin is telling you to stop.
