We all know that sunscreen is a skin care essential. Yet, it might be tempting to splurge on sun protective clothing. These items claim to block out ultraviolet (UV) rays, offering another layer of protection. It seems brilliant – but is it worth the money? Typically, the general rule of thumb is to wear long-sleeved shirts, pants, and long skirts. Wide-brimmed hats offer more protection, especially if you don’t want to cover up. Plus, an average t-shirt has an SPF less than 15, so other forms of protection are a must.1
What Is Sun Protective Clothing?
To boost UV protection, sun protective clothing is often made with tighter weaves and darker colors. It’s rated with an ultraviolet protection factor, or UPF. Think of it like SPF but for clothes. A UPF of 50 means that 1/50th of the sun’s rays pass through. The higher the UPF, the more UV rays are blocked. For sun protective clothes, there’s a total of three categories:
15 – 24: “Good UV Protection”
25 – 39: “Very Good UV Protection”
40 – 50: “Excellent Protection”
What You Need To Know About Sun Protective Clothing
1. UPF Matters
Like SPF, UPF is everything. Anything with a UPF less than 15 should not have the claim of “sun protective.” As for anything more than 50? According to the Federal Trade Commission, anything higher than 50 doesn’t work any better than UPF 50.2
2. Water Lowers UPF
A normal, damp shirt loses its SPF. It’s the same deal with sun protective clothing. When it’s worn damp or wet, the UPF value decreases. Don’t bother with UPF bikinis. Not only is there less coverage, but swimming will just lower the UPF.3
3. Washing Lowers UPF
Repeated washing also lowers the UPF. The same goes for all clothes, so keep this in mind. Repeatedly washing anything will make thin the fabric, letting UV rays pass through.4
4. Dark Fabric Is Better
If you’re going to invest in sun protective garments, choose darker fabrics. Bright colors, like red, are also a smart choice. Compared to whites and pastels, they’ll do a better job at absorbing UV rays.
5. Buy The Right Size
It seems like a no-brainer, but the right size makes it effective. Overstretching actually lowers the UPF rating.5 If possible, go to the store and actually try on clothes.
