As I walk through every golf store here in Charlotte, North Carolina, I see it everywhere.
UPF30 - UPF40 - UPF50 - UPF50+
When I first got into designing golf apparel, I honestly didn't know the difference.
I used to think that the higher the number, the better the protection.
While I wasn't wrong, the differences aren't nearly as dramatic as I thought.
If you've ever wondered whether a UPF50 golf shirt was dramatically safer than a UPF30 golf shirt, like me, you might be surprised by the answer.
What Is UPF & What Does It Actually Mean
UPF stands for Ultraviolet Protection Factor.
It's the measure of how much of the sun's ultraviolet radiation can pass through a fabric and reach your skin.
A UPF30 garment allows approximately 1/30th of UV radiation to pass through the fabric.
A UPF50 garment allows approximately 1/50th of UV radiation to pass through.
Here's what really got my head spinning:
- UPF30 blocks about 96.7% of UV radiation
- UPF50 blocks about 98% of UV radiation
That means both provide excellent protection during a round golf.
The difference is real, but it is much smaller than most marketing teams would lead you to believe.
The Math Behind the Difference
Let's take a look at those numbers a little closer. How much UV radiation is getting through our golf polos?
- UPF30 allows about 3.3% of UV radiation through
- UPF50 allows about 2.0% of UV radiation through
- The difference is about 1.3%.
Again, that's not nothing.
But it also isn't the dramatic leap many golfers imagine when they see that larger number on a tag.
For most golfers spending four to five hours on the course, both ratings provide substantial protection when a golf shirt is worn properly.
The Bigger Problem Isn't Your Shirt
Here is where things get interesting.
Most golfers spend significant time comparing UPF ratings while completely ignoring the areas of their body that receive the most direct sun exposure.
Think about what is exposed during a typical round of golf:
- Your face
- Your ears
- Your neck
- Your hands
- Your calves, if you are wearing shorts
And unlike your shirt, those areas don't come equipped with UPF protection.
The reality is that a golfer wearing a UPF50 shirt without sunscreen is often less protected than a golfer wearing a UPF30 shirt who applies sunscreen properly.
The Mistake Most Golfers Make
The most common sun protection mistake doesn't happen before the round, but during the round.
Many golfers remember to apply sunscreen on the first tee.
Very few remember to re-apply sunscreen two hours later at the turn.
By the time you reach the turn, sweat, humidity, towel use and normal movement have already reduced the effectiveness of most sunscreen products, which are designed to protect for about two hours anyway.
That means that your ears, face, neck and arms may be significantly more vulnerable on the back nine than they were on the front.
If you're serious about protecting your skin, reapplying sunscreen at the turn is often more important than debating whether your shirt is UPF30 vs UPF50.
Building a Smarter Sun Protection Strategy
A better approach may look something like this:
- Wear quality UPF-rated apparel
- Consider adding sun sleeves like SParms to your wardrobe
- Apply sunscreen before your round
- REAPPLY sunscreen at the turn
- Wear a hat that shades your face and ears
- Stay hydrated throughout your round
- Seek shade whenever possible while waiting to play your next shot
While there is no absolute other than playing at night, these habits will do far more for your long-term skin health than chasing the highest UPF number available.
So, Is UPF30 Enough?
For most golfers, yes.
A quality UPF30 golf shirt already blocks nearly 97% of harmful UV radiation and provides excellent protection during a typical round.
UPF50 offers slightly more protection, and there is absolutely nothing wrong with choosing it.
Remember my friends, the difference between the two is often much smaller than the difference between applying sunscreen and forgetting about it entirely.
My biggest takeaway is this:
The best sun protection strategy isn't found on a clothing tag.
It is the combination of quality apparel, sunscreen and smart habits that keep you protected from the first tee to the final putt. Your future self will thank you for it.
