Sun Protection Clothing: Long Sleeve Shirts

Sometimes when you plan on spending the day outside, it seems that applying sunscreen all over your body is too much of a hassle. This is the case where UPF (ultraviolet protection factor) clothing comes in very handy! 

One of the most commonly used pieces of UPF or sun protection clothing are long sleeve shirts (sometimes also called "UV shirts" as they block the UV rays), so let's discover UPF:

✅What type of fabrics offer sun protection in general?

✅How to select the most suited long sleeve UPF shirt for you?

✅Where can you buy comfortable and stylish UPF shirts available online?

Let's find out together!

What is UPF?

UPF clothing is specially designed to provide effective sun protection. It acts as a barrier against harmful UV rays, similar to how sunscreen works but without the need for frequent reapplication. The UPF rating on clothing indicates how well it can block UV radiation, with higher ratings signifying better protection.

UV shirts, also known as sun protection clothing or UPF shirts, are specially designed garments that provide enhanced UV protection. Unlike traditional clothing, UV shirts are made from fabrics specifically engineered to block or absorb UV radiation, thereby reducing the amount of UV exposure to the skin. These fabrics undergo rigorous testing to determine their Ultraviolet Protection Factor (UPF), which indicates the level of UV protection they provide.

How are UPF clothes tested?

The primary standard used for evaluating the UV protection of textiles is the American Association of Textile Chemists and Colorists (AATCC) Test Method 183 and the American Society for Testing and Materials (ASTM) D6603/D6603M standard. These standards outline the procedures for determining the UPF of textiles, which quantifies their UV-blocking capabilities.

In UV clothing testing, both wet and dry conditions are considered, as the effectiveness of the garments may vary depending on moisture levels. While dry testing provides insights into the UV protection capabilities of the fabric under normal conditions, wet testing simulates real-world scenarios where clothing may become wet due to perspiration or water-based activities.

UPF testing with spectrophotometer

One of the most common methods for testing UV clothes involves the use of a spectrophotometer. This instrument measures the amount of UV radiation transmitted through the fabric at various wavelengths. By comparing the UV transmission of the fabric to that of a reference material, the UPF of the fabric can be determined.

UPF fabric swatch testing

Another approach to testing UV clothes involves cutting small fabric swatches and subjecting them to UV radiation in a controlled environment. The UV transmission through the fabric swatch is then measured using a spectrophotometer or similar instrument. This method allows for precise evaluation of the fabric's UV-blocking properties.

UPF fabric field testing

In addition to laboratory-based testing, UV clothes may also undergo field testing in real-world conditions. This involves exposing the garments to natural sunlight and measuring the UV transmission through the fabric using portable UV meters. Field testing provides valuable insights into the performance of UV clothes under actual outdoor conditions.

What does the number after UPF mean?

The numbers following UPF represent the level of protection offered by the garment against harmful ultraviolet radiation. UPF is a numerical rating system that indicates the amount of UV radiation blocked by the fabric, with higher numbers signifying greater protection. Different UPF numbers indicate varying levels of protection against harmful ultraviolet radiation.

Here's a breakdown of what each UPF number signifies:

UPF 15-24 Provides good protection against UV radiation. Allows approximately 6.7% to 4.2% of UV radiation to penetrate the fabric.

Suitable for everyday wear and moderate sun exposure, but additional sun protection measures may be necessary during prolonged outdoor activities or in areas with high UV intensity.

UPF 25-39 Offers very good protection against UV radiation. Allows approximately 4% to 2.6% of UV radiation to penetrate the fabric.

Provides enhanced protection for extended outdoor activities, but sunscreen and other sun protection measures are still recommended, especially during peak sun hours.

UPF 40-49 Provides excellent protection against UV radiation. Allows approximately 2.5% to 2% of UV radiation to penetrate the fabric.

Ideal for prolonged outdoor exposure, offering significant protection against sunburn, premature aging, and skin cancer. However, sunscreen and other sun protection practices should still be employed for comprehensive protection.

UPF 50+ Offers the highest level of protection against UV radiation. Blocks at least 98% of UVB rays and provides exceptional defense against UVA rays as well. Allows only or 2% or less of UV radiation to penetrate the fabric.

Recommended for individuals with sensitive skin, those prone to sunburn, and those seeking maximum protection against the sun's harmful effects. UPF 50+ garments are particularly beneficial for prolonged outdoor activities, water sports, and areas with intense UV exposure.

Do regular clothes provide sun protection?

Regular clothing provides some level of protection against UV rays, but the degree of protection varies depending on the fabric type, color, weave, and thickness. Most standard clothing materials offer limited UV protection, with UPF (Ultraviolet Protection Factor) ratings typically ranging from 5 to 10.

How different factors affect the UPF of regular clothing

Fabric Type

Certain fabrics, such as tightly woven materials like denim or canvas, offer better UV protection compared to lightweight and loosely woven fabrics like cotton or linen. Synthetic fabrics like polyester and nylon also tend to provide higher UPF ratings than natural fibers.

Color

Dark-colored clothing generally offers better UV protection than light-colored clothing. Darker colors absorb more UV radiation, whereas lighter colors may allow more UV rays to penetrate the fabric.

Weave

The tightness of the fabric weave affects its UV protection capabilities. Fabrics with a tighter weave, such as twill or satin weaves, offer better UV protection compared to fabrics with a looser weave, such as plain weaves.

Thickness

Thicker fabrics provide more UV protection than thinner fabrics. Layering clothing can also enhance UV protection by creating additional barriers between the skin and UV radiation.

UPF of different fabrics

It must be kept in mind that these values are approximate and you cannot fully rely on regular clothes for sun protection!

Cotton

Typical UPF: 5-10

Cotton clothing offers minimal UV protection, especially when the fabric is lightweight and loosely woven. Light-colored cotton fabrics provide less UV protection compared to darker colors. Wet cotton fabric may offer even lower UPF due to increased transparency when wet.

Linen

Typical UPF: 5-10

Linen garments, like cotton, provide limited UV protection, particularly when they are lightweight and loosely woven. Light-colored linen fabrics offer less UV protection compared to darker colors.

Polyester

Typical UPF: 15-30+

Polyester fabrics offer better UV protection compared to natural fibers like cotton and linen. Synthetic fabrics like polyester can be tightly woven to enhance their UV-blocking capabilities. Dark-colored polyester fabrics generally provide better UV protection than light-colored ones.

Nylon

Typical UPF: 15-30+

Nylon fabrics offer similar UV protection to polyester and are commonly used in outdoor clothing and swimwear. Nylon can be tightly woven and may also incorporate UV-absorbing additives for enhanced protection.

Spandex/Elastane

Typical UPF: 15-30+

Spandex and elastane are often blended with other fabrics like polyester or nylon in activewear and swimwear. While they offer some UV protection, their UPF may vary depending on the blend and construction.

Denim:

Typical UPF: 15-30+

Denim is a tightly woven fabric that provides moderate UV protection, especially in darker colors. Thicker denim fabrics offer better UV protection compared to lightweight denim.

Wool:

Typical UPF: 20-30+

Wool offers moderate UV protection due to its dense fibers and natural lanolin content. Light-colored wool fabrics provide less UV protection compared to darker colors.

Polypropylene:

Typical UPF: 15-30+

Polypropylene fabrics are often used in activewear and base layers for outdoor activities. These fabrics can be tightly woven to provide good UV protection and moisture-wicking properties.

While regular clothing offers some level of UV protection, it may not provide sufficient protection for prolonged sun exposure or intense UV conditions. For extended periods outdoors or in high UV environments, it's advisable to wear clothing specifically designed for sun protection, such as UV shirts, hats, and pants, with higher UPF ratings (typically UPF 30 or higher). These garments undergo specialized testing to ensure their UV-blocking capabilities and provide more reliable protection against sunburn, premature aging, and skin cancer.
