What is UPF vs SPF?
Compromise
Sun Protection
& Style
Designed for the life you actually live and love outside.
Measures how long before UVB rays cause redness and visible skin damage — on cream alone. Washes off. Wears off. Reapply every two hours.
Topical · DegradesMeasures how much UV radiation — UVA and UVB — a fabric physically blocks. No reapplication. No missed spots. Woven in permanently.
Structural · Always onSame number. Completely different protection. Here's why the UPF sun hat wins.
Blocks UVB only — UVA rays that cause aging and deeper damage still get through
Degrades within 2 hours — heat, sweat, and water strip it away
Easy to miss spots — ears, hairline, back of neck routinely under-applied
Lab results assume a thick even layer — real-world use delivers far less
Blocks both UVA and UVB — full spectrum protection from a single layer
Never degrades — protection is structural, not chemical. Works all day, every day
Zero missed spots — every inch the hat covers is fully protected, every time
Performance is guaranteed — tested and certified, not dependent on application
The real difference: SPF 50 sunscreen blocks about 98% of UVB rays under ideal lab conditions. GoldenOur's UPF 50+ fabric blocks 99% of all UV radiation, both UVA and UVB, every single time you wear it, no reapplication required. More coverage, and it never washes off.
Why UPF 50+ is our standard: GoldenOur's fabric blocks 99% of UV radiation, exceeding the threshold major dermatology associations recommend for daily protection. Protection you'll actually wear is better than maximum protection you leave at home.
Responsible for sunburn and direct DNA damage to skin cells. The primary driver of most skin cancers. SPF addresses this ray only — UPF blocks it too.
Penetrates deeper, causing collagen breakdown and hyperpigmentation. Passes through glass. Present even on cloudy days. Sunscreen often misses it. UPF doesn't.
