Why Doesn't TrailTog Come in More Colors and Prints? The Science Behind UPF Testing

What Does UPF 50+ Actually Mean?

UPF (Ultraviolet Protection Factor) measures how much UV radiation passes through a fabric. To earn a UPF 50+ rating, a fabric must block at least 98% of UVA and UVB rays under standardized laboratory testing.

Importantly, this rating applies to the specific finished fabric system that is tested, not a general category of clothing.

Our Fabric Is Engineered for UPF 50+

One of the most important distinctions in sun-protective clothing is how protection is achieved. Some garments rely on chemical treatments or surface coatings that are applied after the fabric is made. Over time, those treatments can degrade or wash out with repeated wear and washing.

TrailTog is different. Our fabric is selected and engineered to be UPF 50+ at the fiber and construction level. That means:

• There are no UV-blocking coatings added after production
• There are no temporary finishes that wash out over time
• The protection is built into the structure of the fabric itself
• UPF performance is designed to last for the life of the garment

In Short, the Protection Isn't Something Added On

It's part of what the fabric is.

Why Color Matters in UPF Testing

One of the most misunderstood parts of sun-protective clothing is that color is part of performance testing, not just design.

Different dyes and color processes can influence how a fabric interacts with UV radiation. That means changing a color can sometimes change performance enough that it must be re-tested to confirm it still meets UPF 50+ standards.

So instead of assuming all colors behave the same, we verify them.

At TrailTog, Every Color Is Tested

This is where we do things differently. Every TrailTog color is independently tested and verified for UPF 50+ performance. That means:

• We don't assume a new color performs like an existing one
• We don't generalize UPF ratings across fabrics
• We don't skip testing because something "should" behave the same
• We only label something UPF 50+ if that exact color passes testing

If It's a TrailTog Color, It Has Been Tested

No shortcuts. No guessing.

Why Don't We Release Dozens of Prints?

We absolutely understand the appeal of bold prints and seasonal patterns. But every new color or design isn't just a creative decision, it's a testing decision. Each variation requires fabric sampling, production alignment, quality control checks, and independent UPF testing.

That process takes time and investment, which is why we introduce colors thoughtfully instead of rapidly cycling through trends.

Safety Before Trends

We'd rather be consistent than chaotic. We'd rather be tested than trendy. And we'd rather parents trust what they're putting on their child than wonder whether a fun print changes the level of protection.

Because sun protection isn't a fashion category for us, it's the foundation of the product.

Q: Why don't you offer more patterns?

We love patterns, but every new color or print requires independent UPF testing to ensure it meets our protection standards. We only release colors that pass testing as finished products.

Q: Does fabric color affect UPF?

Yes, it can. Color, dye processes, fabric structure, and fiber composition can all influence UV protection. That's why UPF ratings are based on testing, not assumptions.

Q: Does every TrailTog color have the same protection?

Yes. Every TrailTog color has been independently tested and verified to meet UPF 50+ standards.
