UPF By Design

UPF stands for Ultraviolet Protection Factor and is the standard used to measure the amount of UV protection a fabric provides.

Why UPF Matters

A fabric which has an ultraviolet protection factor (UPF) rating means it’s designed to help protect your skin from harmful UV radiation. UV radiation is proven to be detrimental to your skin health and one of the leading causes of skin cancer. Especially when outdoors, it’s important you wear UPF clothing which can keep your skin healthy and cancer free.

All of our products are certified at UPF 50+, the equivalent of a sunscreen that’s SPF 50 or greater. This means all of our products have been tested and certified to block more than 98% of the suns UV radiation. Of course, this only applies to areas of your skin covered by our products.

Unlike most apparel; which often provide far less UV protection than you may think, UPF products can give you the piece of mind to enjoy the outdoors without exposing yourself to the risks associated with UV exposure. This is especially important for those previously diagnosed with melanoma or other forms of skin cancer, which is exactly why we started Rayward Apparel.

How UPF 50 Is Achieved

There are a variety of ways to create clothing which is not only extremely comfortable, but equally as protective.

Often times, it simply comes down to the fabric composition and design. Heavier fabrics often have a higher UPF rating. However, certain fabrics like bamboo and polyester have inherent UV protective characteristics. By using a specific blend of these fibers we are able to achieve a UPF 50 rating without any type of fabric treatment. It can provide a high level of protection while still keeping the clothing lightweight and breathable.

Another way we can achieve sun protection is through a UV treatment. This technique applies a UV treatment to the yarn before the shirt is produced. It’s done in a way that infuses UV protective qualities into the yarn, preventing it from being washed out or diminished over time. This allows us a safe and effective way to ensure sun safety without having to increase the weight of certain fabrics and products.

All of the methods we use to achieve our excellent UPF ratings are in accordance with US guidelines. This ensures everything is responsibly produced and prioritizes the safety and well-being of our customers. 

Lab Testing

All of our products are lab tested and certified in accordance with AATCC Test Method 183. This is the standard test method is used in the US. It measures the UV radiation blocked or transmitted by fabrics intended to provide UV protection.

We send all of our finalized products out to the lab for certification. They take our fabric and use a spectroradiometer to measure the exact amount of UV radiation which was able to pass through it. The result of this test determine the appropriate UPF rating.  Because the color of a fabric can impact the rating, we’ve take the time to certify every fabric AND every color we produce.

To the right is one of the many certifications we keep on hand. This one is specific to our Cool Pink Del Mar UPF 50+ Neck Gaiter.
