Wearing an SPF® 100% cotton t-shirt lowers the amount of harmful UV rays your body absorbs, reducing your risk of getting skin cancer.

The risk is great. On average, someone in the U.S gets skin cancer every 30 seconds. Applying sunscreens and lotions helps, but the most effective and longest lasting sun protection can come from the clothing you and your children wear in the sun. The most commonly worn item of clothing in the sun is the t-shirt. In fact, 1.65 billion t-shirts were sold in the U.S last year. That is an average of 25 per person. For years, people have chosen 100% cotton t-shirts as their favorite outdoor clothing product because t-shirts are comfortable, fashionable and affordable.

The Problem is the vast majority of those t-shirts do not block enough UV to be labeled as sun protective in the US.

Ultraviolet Protection Guidelines for Fabrics & Garments

UV Classification    UPF Ratings

Good UV Protection    15-24

Very Good UV Protection    25-39

Excellent UV Protection    40-50

According to Dr. Lewis Slaten, textile scientist and professor at Auburn University, as well as founder of the International UV Testing Laboratories, most T-shirts offer the same level of sun protection that you get from wearing an SPF (sun protective factor) 6 to10 sunscreen. That is less than the minimum SPF 15, which doctors and scientists recommend for sunscreens. That’s clearly not good enough.

Now for the good news!

SPF® 100% cotton t-shirts combine the comfort and feel of 100% cotton with top UV-rated, UPF 40-50+, Excellent UV Protection. That means most SPF® t-shirts block over 97% of UV even after 40 home launderings and 100 hours of UV exposure. All 70+ colors of SPF® t-shirts are UV tested, UV rated and certified in the U.S., by the International UV Testing Laboratory and meet or exceed all U.S testing and labeling UV standards. *

Two types of UV are linked to skin cancers:

  • UVA - is the deeper-penetrating form of UV which is closely associated with deadly melanomas and
  • UVB – which is responsible for sun burns/tans and for less-life threatening basal and squamous skin cancers.
  • There are significant differences between UPF and SPF ratings:
  • SPF ratings are used only for sunscreens and lotions while UPF is used only for fabric and clothing,
  • UPF ratings measure both UVA and UVB while SPF ratings measure only UVB and
  • Clothing needs to achieve at least a UPF (ultraviolet protection factor) rating of 15 before it can claim to be sun-protective.
  • Knowing the level of UV protection that your clothes provide is especially important for children, people suffering from certain ailments or diseases and people taking certain types of medications which can increase sensitivity to the sun. These are just a few of the commonly used drugs that can cause photosensitivity reactions in some people.

People around the world are becoming more aware of the need to protect themselves and their families in the sun by wearing sun-protective clothing, in addition to applying sunscreen. Parents are learning that their children need to be shielded from the sun’s damaging UV rays early and throughout their lives because most of the skin damage (80%) that leads to skin cancer occurs before the age of 18. Cancer societies and associations around the world are actively recommending that people wear sun protective clothing. Sun protective clothes are now easier for consumers to find as major international companies, such as Nike, LandsEnd, Columbia Sportswear, LL Bean, REI and others, are joining the many specialty catalog and outdoor retailers that have been offering a variety of apparel products promoted and labeled as sun-protective. The experts are predicting that within the next several years all clothing that can be, will be labeled with a UV rating.

SPF® 100% cotton t-shirts are the perfect weight, pre-shrunk for perfect fit, available in over 70 colors that are color dyed and UV finished in the U.S and most are top-UV rated, UPF 40-50.

SPF® adult short-sleeve shirts are priced as low as $9.95, youth short-sleeve shirts at $8.99, adult and youth long-sleeve shirts at $14.95 when you purchase 4 or more shirts in any style or color.

SPF® t-shirts offer better sun protection than you get from a “sun protective” $35 to $80 nylon/polyester UPF-30 rated shirt. As you know, there is no substitution for the feeling of cotton next to your skin. SPF® t-shirts are now available online at

A portion of the proceeds from the sale of SPF® t-shirts are donated to the Melanoma Research Foundation
