Sun protection is an important part of staying healthy and looking great. But with the current summer heat, it can be hard to stay cool while being out in the sun. UPF clothing is a great solution to this problem, providing excellent protection from the sun's rays while still allowing you to look stylish and feel comfortable. 

UPF clothing, also known as Ultraviolet Protection Factor clothing, is apparel specifically designed and tested to block out the sun's harmful UV rays. 

The fabric is tightly woven for maximum protection and typically has a UPF rating of 30-50 or higher, which represents the amount of UV radiation that can penetrate the fabric. UPF clothing offers significantly better protection than regular clothing, which usually only stops around 5-10% of UVA/UVB rays.

But how exactly does UPF clothing work? In this article, we'll explore what UPF clothing is and how it works to keep you safe when you're out in the sun.

The Science Behind UPF Protection

Generally speaking, the higher the UPF rating, the greater level of sun protection you get from your clothing. It's important to note that all fabrics offer some degree of UV protection, but those with a UPF rating of 30 or higher provide more complete coverage.

So how does this work

Well, fabrics with high UPF ratings are tightly woven and/or treated with special UV-blocking additives which help filter out harmful rays. This means that certain wavelengths of light can't penetrate the fabric and reach your skin, helping you stay safe from sunburns and long-term skin damage associated with excessive exposure to UV radiation. 

And because these clothes are also designed to be comfortable and durable, they're perfect for outdoor activities like hiking or swimming.

UPF clothing is an essential item for anyone who spends time outdoors in sunny climates or areas prone to high levels of UV radiation. With its superior protection and stylish designs, it allows us to have fun without worrying about our safety or sacrificing our sense of style. 

Whether you’re headed on vacation or just getting ready for a day trip to the beach, make sure you pack some UPF clothes!

Types of Fabrics with UPF Protection

Types of Fabrics with UPF Protection

When it comes to UPF protection, not all fabrics are created equal. Different materials provide varying levels of coverage and comfort, so it’s important to know which ones offer the best protection. 

Here’s a look at some of the most common fabrics with UPF ratings:

    • Bamboo: Of all the natural fibers, viscose from bamboo is one of the most breathable and comfortable options for UPF clothing for men and women. It typically has a UPF rating of 30-50, depending on how tightly woven it is. Bamboo also absorbs sweat easily and won’t irritate your skin like some other fabrics can.

    • Synthetic Fabrics: Synthetic fibers such as polyester or nylon are naturally UV resistant, and can also be treated with special UV-blocking chemicals that help raise their UPF rating even more. This makes them an excellent choice for those who need extra sun protection while engaging in outdoor activities like swimming or running. The only downside is that synthetic fabrics can be less breathable than natural fibers.

    • Wool: Wool is another natural fiber that offers good sun protection, depending on how tightly woven it is. While wool is lightweight and very breathable, it can also be more expensive than other types of fabric and may require extra care when washing it.

UPF clothing plays an important role in helping us protect ourselves from harmful UV radiation while we enjoy time outdoors. So regardless of what type of fabric you choose, make sure you get something with a high enough UPF rating for your needs and activities!

Tips for Buying and Wearing UPF Clothing

When it comes to buying and wearing UPF clothing, there are a few key tips to keep in mind. 

    • First, choose fabrics that are lightweight and breathable so you can stay comfortable in the sun. 

    • Also, make sure to read the UPF rating of each garment before making a purchase so you know how much protection it offers. 

    • Finally, look for items that fit your personal style so you feel confident wearing them.

In addition to selecting the right garments, it’s important to wear your UPF clothing correctly. 

    • For maximum protection, cover as much skin as possible by wearing long sleeves and pants or skirts that reach below the knee. 

    • Also, make sure to wear UPF accessories such as a wide-brimmed hat and sunglasses with UV-filtering lenses when spending time outdoors.

By following these simple tips and taking care of your UPF clothing properly, you can enjoy protection from harmful UV rays without sacrificing comfort or style.

Environmental Impact of UPF Clothing

UPF clothing is an eco-friendly and highly effective way to protect your skin from the sun's harmful UV rays. Not only does UPF clothing provide excellent sun protection, but it can also help reduce your environmental impact. Here’s how:

    • First, unlike traditional sunscreen, UPF clothing won't wash off or evaporate into the environment. This means the protection will last for many years, reducing the need to repurchase new products and helping you save money in the long run. 

    • Additionally, UPF garments are often made with sustainable materials such as recycled polyester or bamboo that require less water and energy during production than traditional fabrics.

Overall, investing in UPF clothing can be beneficial both for your health and the environment – making it a smart choice when it comes to sun safety!


In conclusion, UPF clothing can be a great way to protect yourself from the harmful effects of the sun's UV rays. It is important to look for clothing items with a UPF rating of at least 30 or higher to ensure maximum protection. 

While UPF clothing items may be more expensive than regular clothing, they are worth the investment in terms of protecting your health. 

Additionally, UPF clothing items are suitable for all climates and there are plenty of options available when it comes to swimming attire. It is important to note that wearing UPF clothing does not come with any known health risks. 

So, if you want to stay safe and healthy while enjoying the outdoors, investing in some UPF-rated clothes could be a great idea! Contact Rayward Apparel for more information!
