7 Stylish Rash Guards For Your Next Beach Day

If you think a white cotton tee worn over your bikini is protecting your skin from the sun’s harmful rays, think again. The fact is that not all fabrics are created equal. Some are nearly translucent, some are impermeable, and some are UPF 50.

UPF stands for Ultraviolet Protection Factor and has to do with how well a fabric protects your skin from the sun. Fabrics with an UPF of 50 have a very tight weave, like corduroys or dungarees. “The concept of UPF 50 fabrics and swimwear is that you’re getting really powerful protection that’s screening out 98 percent of UVA and UVB rays but that’s a light, breathable, quick-drying fabric,” says Whitney Bowe, M.D., a board-certified dermatologist in New York City.
