Picture this: You step outside for a walk, run a few quick errands, or grab lunch alfresco. Wearing a long-sleeve T-shirt or a light button-down, it feels like your skin is covered and protected from the sun. But is that really the case?
While any layer of clothing offers some level of sun protection, not all fabrics are created equal. Some provide excellent UV coverage, while others allow harmful rays to pass through. So the real question is: do you need sunscreen under your clothes?
Do You Need Sunscreen Under Regular Clothing?
If your clothing isn’t labeled as UPF-rated, you’re likely getting only minimal protection-especially if you're wearing lightweight, loosely woven fabrics like cotton, linen, or rayon. Even synthetic materials like polyester, which many assume offer solid UV protection, may not provide consistent coverage unless they're specifically designed for it. These materials may feel breathable and comfortable, but they can still allow UV rays to reach your skin.
If you’ll be outdoors for an extended period, applying sunscreen under your clothing can help reduce exposure. Whether you’re hiking, gardening, playing or spectating outdoor sports, those hours in the sun can add up quickly. Still, applying sunscreen before getting dressed isn’t always convenient. It can feel greasy, messy, and uncomfortable—especially in hot or humid weather.
That’s where UPF clothing comes in.
Why UPF Clothing Is a Smarter Choice
UPF stands for Ultraviolet Protection Factor. It measures how effectively a fabric blocks UV radiation from reaching your skin. Here's a quick breakdown:
- UPF 30 blocks about 96.7% of UV rays
- UPF 40 blocks 97.5% of UV rays
- UPF 50+ blocks at least 98% of UV rays
Unlike regular clothing, UPF-rated apparel is engineered to provide consistent, broad-spectrum protection. These items are tightly woven and sometimes treated with UV-blocking technology to help prevent both UVA and UVB rays from penetrating through. And unlike sunscreen, UPF clothing doesn’t lose effectiveness after a few hours or require reapplication.
If you’re wearing a UPF 50+ shirt, you're blocking nearly all UV rays on the areas it covers. That means there’s no need to apply sunscreen underneath—making your daily sun protection routine easier and more reliable.
So, is UPF clothing worth it? Yes, especially when UPF clothing, like Essuntials, is designed for comfort. It’s soft, breathable, and easy to wear for hours without the sticky residue or potential staining that sunscreen can leave behind. For those who want dependable protection without interrupting their lifestyle, UPF clothing offers a practical, stress-free solution.
When to Add Sunscreen to Your Routine
While UPF clothing offers excellent protection, sunscreen is still necessary for areas that aren’t covered—like your face, neck, ears, hands, and legs—especially if your clothing isn’t UPF-rated, shifts during the day, or you’ll be outdoors for hours. Wearing sunscreen under regular clothing can be helpful in those situations, but it’s not always convenient or comfortable. UPF clothing is designed to make sun protection easier, offering consistent coverage without the mess or need for frequent reapplication.
How to Combine UPF Clothing and Sunscreen
Think of UPF clothing and sunscreen as a team. Together, they provide full-spectrum protection. Here’s how to build a well-rounded routine:
- Wear UPF 50+ clothing to shield your arms, legs, shoulders, and torso
- Apply broad-spectrum sunscreen to exposed skin like your face, neck, ears, hands, and ankles
- Add a wide-brimmed hat for extra coverage of your scalp and face
- Use UV-blocking sunglasses to protect your eyes and the delicate skin around them
- Seek shade when possible, especially between 10 a.m. and 4 p.m. when UV rays are strongest
These habits help protect against sunburn, premature aging, and long-term skin damage without complicating your daily routine.
Common FAQs About Sunscreen and Clothing
Here are answers to a few common questions people have about clothing, sunscreen, and how the two work together.
Q: Can UV rays pass through regular clothing?
Yes. Many everyday fabrics, including natural fibers like cotton, linen, and rayon, as well as synthetics like polyester, can allow UV rays to reach your skin—especially when the fabric is light-colored, thin, or loosely woven. Unless a garment is specifically UPF-rated, it may not provide adequate protection from sun exposure.
Q: Do I need sunscreen under a cotton shirt?
If the shirt doesn’t have a UPF rating and you’ll be outside for a while, it’s a good idea to apply sunscreen underneath. Regular cotton may not block enough UV rays.
Q: What types of clothes offer the best sun protection?
UPF-rated clothing, particularly those rated UPF 50 or higher, is designed to block 98% or more of UVA and UVB rays, offering reliable broad-spectrum coverage.
Q: How is UPF different from SPF?
UPF refers to how much UV radiation a fabric can block, while SPF measures how long a sunscreen protects your skin from UVB rays. Sunscreens only offer protection from UVA rays if they are specifically labeled as broad-spectrum.

The Bottom Line
If you’re wearing high-quality UPF-rated clothing, you don’t need sunscreen underneath it. But you should still protect any uncovered skin. If your clothing isn’t UPF-rated or you’ll be in the sun for a long time, sunscreen underneath adds valuable protection.
UPF clothing simplifies sun protection. It gives you reliable, comfortable coverage so you can enjoy your day outdoors without second-guessing your routine. Whether you're walking the dog, exploring the farmer's market, or simply enjoying life in the sunshine, it's a smart and easy way to stay protected.
