Sunscreen is a good start, but, it's not enough. Here's the real difference between SPF and UPF, why golfers are uniquely at risk, and what actually protects you over a four-hour round.
If you've ever reached the back nine and realized you forgot to reapply sunscreen, or simply assumed your regular polo was doing enough, this article is for you. Most golfers understand that sun protection matters. Far fewer understand the difference between the two main tools available to them, or why one consistently outperforms the other on the course.
Let's break it down.
What Does SPF Actually Mean?
SPF stands for Sun Protection Factor, and it only applies to sunscreen products, lotions, sprays, and creams you apply to exposed skin. The number tells you how much longer you can stay in the sun without burning compared to wearing nothing at all.
SPF 30 blocks about 97% of UVB rays. SPF 50 blocks about 98%. The difference sounds small, but for someone spending four or five hours outside, it adds up.
Here's the critical thing most people miss: SPF only measures protection against UVB rays - the rays that cause sunburn. It says nothing about UVA rays, which penetrate deeper into the skin, cause long-term damage, accelerate aging, and are strongly linked to melanoma. To get coverage from both, you need a broad-spectrum sunscreen, and you need to reapply it every 90 to 120 minutes, or immediately after sweating heavily.
A typical round of golf takes four hours. Most sunscreen wears off or sweats through in under two. That means without reapplication, you're unprotected for more than half your round, on your most exposed surfaces.
What Does UPF Mean?
UPF stands for Ultraviolet Protection Factor, and it applies exclusively to fabric and clothing. Unlike SPF, UPF measures protection against both UVA and UVB radiation, the full UV spectrum.
A UPF 50+ rated garment blocks 98% of UV radiation, allowing only 1/50th to pass through to your skin. The protection isn't applied, it's woven into the fabric itself. It doesn't sweat off. It doesn't wear down over a round. It doesn't require reapplication. As long as you're wearing the shirt, you're protected.
That's a meaningful difference when you're outside for hours at a time.
Why Golfers Are Especially at Risk
Golf is one of the highest UV-exposure sports there is, and most players don't treat it that way.
A round of golf typically runs three to five hours, often between 9am and 3pm when UV index levels are at their peak. There is minimal shade on most courses. And unlike running or cycling, golf involves extended periods of standing still in direct sunlight, waiting, and walking open fairways with no overhead cover.
Your forearms are your most exposed surface during a round. Think about your stance, your backswing, your follow-through. Your arms are extended and facing upward toward the sun for hundreds of repetitions over a round. Short sleeves leave that entire surface unprotected.
In the Okanagan, where UV index regularly hits 8 to 10+ on summer afternoons, the risk is even more pronounced. The desert climate, high elevation, and reflective lake surfaces combine to create some of the highest UV exposure conditions in Canada.
What to Look For in a UPF Golf Shirt
Not all UPF claims are equal. The term gets used loosely in the apparel industry, and not every brand backs it up with independent verification. Here's what actually matters:
Third-party lab testing. A UPF claim on a label means very little without independent verification. Look for brands that have had their fabrics tested by an accredited laboratory, not just self-assessed. The test measures actual UV transmission through the fabric under real conditions.
Long sleeve coverage. A short sleeve UPF polo protects your shoulders but leaves your forearms, your most exposed surface completely unprotected. For meaningful protection during a round of golf, long sleeve is the right choice.
Lightweight, breathable fabric. UPF protection should not mean overheating. Modern performance UPF fabrics are lightweight, moisture-wicking, and designed for warm-weather activity. If a shirt is uncomfortable in summer heat, you won't wear it and protection you don't wear does nothing.
A note from our founder
In 2018, I was diagnosed with malignant melanoma. I live in Penticton, BC, one of Canada's sunniest regions, and after my diagnosis I was genuinely afraid to go outside. I couldn't find a UPF golf polo I actually wanted to wear. Everything I found looked clinical or uncomfortable. So I made Enjoy the Vu: third-party lab-tested UPF 50+ polos designed for golfers who refuse to give up the game they love.
Every shirt we make is the shirt I needed in 2018.

The Bottom Line: Use Both
SPF and UPF aren't competitors, they're teammates. Use broad-spectrum sunscreen on your face, neck, and the back of your hands (areas clothing can't cover), and wear a UPF 50+ long sleeve polo for your arms, shoulders, and upper body. Together, they give you comprehensive coverage across your entire round without gaps.
Sunscreen is still essential. But for the areas you can cover with clothing, UPF fabric is more consistent, more convenient, and more reliable than any lotion over a full round of golf. It doesn't wear off at the 14th hole. It doesn't need a touch-up after a sweaty par-5. It just works.
Protection that works all day, every hole, without thinking about it. That's the whole idea behind Enjoy the Vu.
