Not all clothing is sun protective, and not all sun protective clothing is created equal.
Innovation is at the heart of Coolibar’s philosophy. We’re relentless about developing fabrics that matter in contemporary styles made for movement, fitness and fun. We believe in an active, outdoor life.
We've developed industry-leading fabrics with performance features like lightweight, soft, breathable, stretch, moisture-wicking, fast drying, cooling, water repellant, anti-microbial – all designed for movement, fitness and fun. Each proprietary fabric type is designed for a very specific function and outdoor activity. For example, our swimming and snorkeling fabrics are chlorine- and saltwater- resistant and dry quickly.
What makes a better sun protective fabric?
Technical innovation and independent third-party testing ensures our fabrics are UPF 50+. Our fabrics use a combination of weave (tighter is better), color, weight and additions of the best active ingredients found in sunscreens, millions of the sun-bouncing minerals, titanium dioxide and zinc oxide infused at the fiber or fabric level. Even with multiple washings and exposure to sweat, chlorine and salt – our sun protection never washes out.
We NEVER say SPF. Fabric is UPF. Lotion is SPF.
If you see clothing brands labeled as SPF protection, it’s not accurate for fabrics. SPF stands for Sun Protection Factor which measures the amount of time it takes for sun-exposed skin protected with sunscreen or lotion type products to redden from UVB (“burning”) rays. UPF is a broad-spectrum UVA and UVB measure for fabric, and it rates the amount of UV radiation that penetrates a fabric and reaches the skin. A garment with a UPF of 50 only allows 1/50th of the UV radiation falling on the surface of the garment to pass through it. It blocks 49/50ths or 98% of the UV radiation. Clothing brands that cite SPF are not full spectrum protection.
Isn't My Cotton Tee Enough? In a word, no.
An average cotton t-shirt may not safeguard you at the beach, let alone on the street. When dry, a white cotton t-shirt only provides an ultraviolet protection factor (UPF) of 5-7*. Even worse, when wet from the pool, the protection level drops to about UPF 3, exposing us to UV radiation we may be unaware of.
Today, 90% of skin cancers and premature aging are a result of compounded UV exposure. Coolibar’s ZnO t-shirts, polos, tunics, cover-ups, dresses, hoodies and pants are super soft, comfortable and UPF 50+, blocking 98% of UV rays wet or dry. All our fabrics are guaranteed UPF 50+, from the first time you wear our product to the day you retire it.
Since UV damage is cumulative and irreversible, starting kids and teens with UPF clothing provides the best option when it comes to outdoor activities. With ultra-soft fabrics, like our ZnO, kids fall in love with Coolibar t-shirts which we design to keep them sun safe year-round.

Why are clothes called UPF instead of SPF?
Between UPF and SPF, the concept is essentially the same, to protect your skin from ultraviolet radiation. What SPF is to lotions, liquids and serums, UPF is to fabrics and clothing. SPF only measures sunscreen protection from UVB rays, the burning rays. When applied correctly, SPF 30 blocks 97% of UVB rays. UPF 50+ measures light transmittance, blocking 98% of UVA and UVB rays. Coolibar fabrics exceed all published American and Australian standards.
How is Coolibar ZnO t-shirt fabric developed?
ZnO is our unique blend of cotton, bamboo viscose (a natural UV fighter) and spandex fabric, embedded with millions of zinc oxide minerals at the fabric level. Zinc Oxide protects against UVA and UVB rays and has many skin comforting qualities, often used on the most sensitive skin types. So soft and soothing, our Coolibar ZnO t-shirts are sure to become your everyday favorite.
Guaranteed UPF 50+ for the life of your shirt, pants, dress or...
Tested more than any other brand, endorsed by experts worldwide and recommended by dermatologists - Coolibar guarantees UPF 50+ protection in our fabrics from the first day our product is worn until the day your garment is retired.
It’s vital that all our clothing is UPF 50+ so everyone can live outside safely in the sun. Many UV brands only measure themselves against one standard for UV safety, while we invest in testing all our fabrics multiple times against multiple UPF standards for UV transmittance and safety. UV rays react differently to colors, patterns and fabrics, so we are cautious and use a protocol of testing every fabric we make in every color and pattern we create. And we do this for every season, every collection and every new production run. We use independent, third-party testing to evaluate fabric samples three times over and measure performance against U.S. standards as well as Australian/New Zealand UPF rating standards. That means, when you’re wearing a Coolibar shirt, we can report the testing data to on fabric it was made from.
The “+” means our fabrics are tested at highest possible UPF 50+ standards.
Testing evaluates UV transmittance before and after life cycle tests – laundering, sunlight and chlorinated water. Coolibar’s level of sun protection is measured against all worldwide published rating standards for UPF 50+. We’ll always test our fabrics for UPF 50+ protection like your life depends on it – because it does.
