Golfers obsess over the details — the right ball, the right shaft, the right line on a six footer. But one detail is often overlooked: the fabric of the shirt you wear for four to five hours under open sky.

At first glance, a golf polo is just a polo. But the material it’s made from can dramatically affect comfort, performance, and even long term skin health. Cotton has been the traditional choice for decades, but modern performance fabrics have taken over for a reason.

And here’s the part most golfers never realize: The majority of golf polos on the market — especially cotton ones — offer little to no UV protection.

Let’s break down why that matters, and why performance fabrics are becoming the new standard for serious players.

Cotton: Classic Feel, Limited Function

Cotton is familiar, soft, and comfortable in everyday life. But on the golf course, its weaknesses show quickly. 

1. Cotton absorbs sweat — it doesn’t move it away

Once cotton gets wet, it stays wet. The shirt becomes heavier, clingy, and uncomfortable. On a warm day, this can ruin focus and rhythm.

2. Slow drying time

A cotton polo can stay damp for the entire round, especially under a golf bag strap or during humid conditions.

3. Loses shape over time

Cotton tends to stretch, shrink, or sag after repeated washing — collars and hems suffer the most.

4. Almost no UV protection

This is the big one. Most cotton polos provide minimal or zero UPF rating, meaning UV rays pass through the fabric easily. Considering golfers spend hours in direct sunlight, this is a serious drawback.

Cotton feels good — but it’s not built for performance, and it’s definitely not built for sun exposure.

Performance Fabrics: Engineered for the Course

Modern technical fabrics, like the Stormtech micro pique polyester used in the Underdog Men’s Signature Polo, are designed specifically to solve the problems cotton can’t.

1. Moisture-wicking technology keeps you dry

Stormtech’s H2X DRY® system pulls moisture away from the skin and evaporates it quickly. The result: a cooler, lighter, more comfortable feel from the first tee to the clubhouse.

2. Lightweight and fast-drying

Performance micro pique dries several times faster than cotton, making it ideal for warm rounds, travel, and repeated use.

3. Built-in stretch for unrestricted movement

Mechanical stretch allows the fabric to move naturally with your swing — no pulling, no resistance, no stiffness.

4. Snag-resistant durability

Unlike cotton, performance fabrics maintain their shape and structure even after dozens of rounds and washes.

**5. UPF 40+ sun protection — a feature most polos lack

This is where performance fabrics truly stand apart. The Underdog Signature Polo includes UPF 40+, meaning it blocks the majority of harmful UV rays.

Most golf polos — even expensive ones — do not include any certified UV protection. This makes a UPF-rated performance polo not just a comfort upgrade, but a health upgrade.

Why Underdog Chose Performance Fabric Over Cotton

The Underdog philosophy is simple: golf isn’t about perfection — it’s about showing up, grinding, learning, and coming back for more. The gear you wear should support that mindset, not hold you back.

That’s why the Underdog Men’s Signature Polo is built with:

• Stormtech H2X DRY® moisture-wicking technology
• Lightweight micro pique performance fabric
• Mechanical stretch for natural movement
• Snag-resistant durability
• UPF 40+ sun protection
• A tailored, athletic fit that holds its shape
• An embroidered Underdog logo as a reminder of the mindset

This isn’t just a polo — it’s a piece of equipment. 

So Which Is Better? Cotton or Performance Fabric?

If you want: 

• a classic feel
• casual comfort
• everyday wear

→ Cotton works. 

But if you want:

• to stay dry
• to move freely
• to avoid heavy, sweaty fabric
• to protect your skin from UV rays
• to perform your best on the course

→ Performance fabric wins every time.

And if you want a performance polo that actually includes certified UV protection — something most brands skip — the Underdog Signature Polo stands out even more.

Final Thought: Choose a Polo That Works as Hard as You Do

Golf is a long game — physically and mentally. Your shirt should help you stay comfortable, protected, and focused, not distract you or weigh you down.

Most polos don’t offer UV protection. Most polos don’t manage moisture well. Most polos aren’t built for the grind of real golf.

The Underdog Men’s Signature Polo is.

Because the game isn’t about being flawless — it’s about showing up, taking another swing, and doing it all again next weekend.
