Why wear a women's sun shirt?
Sun exposure is the leading cause of premature aging and skin cancer. While sunscreen is essential, its effectiveness diminishes over time and requires frequent reapplication. Sun shirts, on the other hand, offer consistent protection without the hassle of reapplying sunscreen. Here are some key benefits:
UPF Protection: Sun shirts are rated with an Ultraviolet Protection Factor (UPF), which measures their ability to block UV rays. A UPF 50+ rating means the fabric blocks over 98% of harmful rays.
Breathability & Moisture Wicking: Many sun shirts use lightweight, moisture-wicking fabrics that keep you cool and dry, making them ideal for warm weather.
Eco-Friendly Options: Many brands now offer sustainable fabrics like recycled polyester and organic cotton.
Versatility: Modern designs blend function with fashion, making them perfect for outdoor adventures, casual wear, and even work settings.

Understanding UPF Ratings and Testing
UPF, or Ultraviolet Protection Factor, measures the effectiveness of fabric in blocking ultraviolet (UV) radiation. Unlike SPF (Sun Protection Factor), which applies to sunscreen and measures protection against UVB rays, UPF accounts for both UVA and UVB rays. The rating system is:
UPF 15-24: Good protection, blocking 93-95% of UV radiation
UPF 25-39: Very good protection, blocking 96-97% of UV radiation
UPF 40-49: Excellent protection, blocking 97.5% or more of UV radiation
- UPF 50+: The best defense against harmful sun exposure, blocking 98% of UV radiation. All JOJU women's sun shirts are rated UPF 50+
How are SUN Shirts tested for upf ratings?
Fabrics undergo rigorous testing to receive a UPF rating. Standard tests include
Laboratory Testing: Textiles are exposed to UV radiation using a spectrophotometer to measure the amount of UV blocked versus what penetrates through the fabric.
Real-World Testing: Some brands test garments in outdoor environments to simulate prolonged sun exposure.
Fabric Aging Tests: Since washing, stretching, and wear can impact UPF, some testing protocols include simulating these factors to determine long-term protection levels.
"Sun-protective clothing is the simplest way to stay safe; unlike sunscreen, you never need to reapply."
Choosing the Right Women's Sun Shirt Fabric
A shirt's fabric determines its sun protection capabilities as well as its comfort and durability. Here’s what to look for:
Synthetic vs. Natural Fibers: Synthetic fabrics like polyester and nylon offer superior moisture-wicking and durability. Natural fibers like cotton are less naturally sun protective.
Cooling Technology: Some brands incorporate cooling technology to help regulate body temperature.
Stretch & Fit: A blend of spandex or elastane adds stretch for comfort and mobility, especially important for activities like tennis, hiking and yoga.
Women's Sun shirt Fit & Style Considerations
When shopping for women's sun shirts, think about how you plan to use them & how they will fit into your lifestyle. Things to think about:
- Durability of Sun Protection. Does your sun shirt gets its UPF protection from its fibers or from a treatment applied at a mill? If it's from fibers, protection will last the lifetime of the shirt.
- Fit. Do you prefer a slim fit or a looser, more relaxed fit.
- Breathability. Look for a women's sun shirt that
- Ease of Care. Look for a women's sun shirt that is machine washable & dryable for easy, repetitive use.

Women's sun shirt FAQs
What is a UPF rating, and why does it matter?
A UPF (Ultraviolet Protection Factor) rating measures how effectively a fabric blocks UV radiation. A UPF 50+ rating means the fabric blocks over 98% of harmful rays, providing excellent sun protection.
How do I know if a sun shirt is truly protective?
Look for certified UPF ratings from reputable brands, and check if the shirt has been tested in a laboratory setting. Dense weaves, darker colors, and treated fabrics also enhance sun protection.
Do sun shirts replace sunscreen?
No, sun shirts provide consistent UV protection, but exposed areas like the face, hands, and legs still require sunscreen for complete sun safety.
Can I wear a regular long-sleeve shirt instead of a sun shirt?
A regular long-sleeve shirt provides some coverage, but it may not offer the same level of UV protection as a purpose-built sun shirt with a high UPF rating and moisture-wicking properties.
How do I care for my sun shirt to maintain its UPF protection?
Wash in cold water, avoid fabric softeners, and line dry when possible. Some sun shirts use chemical treatments for UV protection, which can wear off over time, so follow the manufacturer’s care instructions.
