THE BASICS

What the Heck Is UPF, Anyway?

UPF stands for Ultraviolet Protection Factor, which is basically SPF's overachieving cousin — but for clothing instead of sunscreen.

Why UPF Clothing Matters More Than You Think

You probably think you're protected in a regular cotton tee. A standard shirt only offers the equivalent of SPF 5–7. That's basically sunscreen's version of a participation trophy.

Frequently Asked Questions

What's the difference between UPF and SPF?

SPF (Sun Protection Factor) measures protection for sunscreens applied to skin, while UPF (Ultraviolet Protection Factor) measures protection for fabrics. UPF rates both UVA and UVB protection, whereas SPF only measures UVB. UPF 50+ blocks 98% of UV rays — and unlike sunscreen, it doesn't wear off or need reapplying.

Does UPF protection wash out over time?

Quality UPF clothing like Island Frog maintains its protection wash after wash. The UV protection is built into the fabric structure and special fibers, not applied as a coating. However, heavily worn or damaged fabric may lose some effectiveness over time.

Can I still get vitamin D while wearing UPF clothing?

Yes! UPF clothing covers specific areas, leaving other skin exposed. You only need about 10-15 minutes of sun exposure on uncovered areas a few times a week for adequate vitamin D. Your face, hands, and legs often remain exposed.

Is darker colored UPF clothing more protective?

Not necessarily with quality UPF fabrics. While darker colors in regular clothing do block more UV, properly engineered UPF clothing provides consistent protection regardless of color. Island Frog shirts are rated UPF 50+ across all color options.

Do I still need sunscreen with UPF clothing?

You should still apply sunscreen to exposed areas not covered by clothing — face, neck, hands, and legs. The combination of UPF clothing and sunscreen on exposed skin provides the best overall protection.

Is UPF clothing hot to wear?

Not at all! Modern UPF fabrics like Island Frog's are specifically designed to be lightweight, breathable, and moisture-wicking. They actually help keep you cooler than getting sunburned, which raises your body temperature.

How do I know if my regular clothes have UV protection?

Most regular clothing offers minimal protection (SPF 5-7 for a white cotton tee). Hold fabric up to light — if you can see through it easily, UV rays pass through too. For guaranteed protection, look for clothing specifically labeled with a UPF rating.

Who should wear UPF clothing?

Everyone who spends time outdoors! It's especially important for those with fair skin, outdoor workers, athletes, kids, anyone with a history of skin cancer, and people taking medications that increase sun sensitivity.
