UPF clothing works thanks to advanced fabric construction and materials—denser weaves, unique fibers, and special treatments provide superior protection. Key factors include:

• Tighter weave: Fabrics with tighter weaves leave less space for UV rays to pass through.
  
• UV-blocking additives: Some UPF garments are treated with sun-blocking chemicals during production.
  
• Natural or synthetic materials: Fabrics like polyester and nylon typically fare better in UV resistance compared to natural materials like cotton. Whether you’re hiking, swimming, or just spending time outdoors, UPF clothing provides an extra layer of reliable defense against harmful UV exposure. 

UPF clothing offers durable protection, but its effectiveness can depend on several factors, including fabric quality, frequency of wear, and how you care for it.

Unlike sunscreen, UPF isn’t something you apply—it’s embedded in the fabric itself. However, improper care may reduce effectiveness. Some UPF garments, especially those treated with UV-blocking chemicals, may gradually lose their effectiveness after repeated washes. Our entire range of UPF clothing guarantees UV protection by construction without any chemical treatment, meaning that the UPF never washes out, even with regular use.

Exposure to UV rays isn’t just a summer concern—they can be just as strong on cloudy days or during colder months.

UPF clothing is especially necessary in these situations:

• Outdoor activities: Whether hiking or running, sun exposure calls for added protection.
• Sailing and beach days: Reflective surfaces like water and sand amplify UV exposure. Protect yourself with lightweight UPF clothes.
• High altitudes: UV radiation increases with elevation, making sun protection crucial during mountain trips, like ski touring. 

Top tip: if you feel a bit sweaty in the heat, pick UPF clothing with moisture-wicking qualities, which will keep you cool, dry, and protected.

It’s easy to think that sunscreen isn’t necessary, but you should still apply it. Whether you’re relaxing at the beach or working up a sweat on the trail, parts of your body can still get exposed to direct sunlight (especially areas like the neck, face and wrists).

For non-UPF clothing, darker colors like black and navy tend to block more UV rays than lighter shades. When it comes to UPF clothing specifically, the color should not affect the level of UV protection. At Helly Hansen, all our UPF clothing is tested to ensure that every piece, regardless of color, offers the same level of protection.

While a simple long-sleeved shirt might provide some shield against the sun, it’s no match for the specially designed defense of UPF clothing. UPF fabrics are tested and rated to ensure consistent protection, something that regular clothing cannot guarantee. 

Technically, all fabrics block UV rays to some extent, but most everyday clothing lacks the density or treatment required to meet UPF certification standards. Even items like thin t-shirts or loosely woven fabrics leave you vulnerable to UV exposure. So when it comes to reliable protection, investing in UPF clothing is the smarter, safer choice. 

Like all garments, UPF clothing should be cared for in the right way to maintain its effectiveness.

1. Read the label: Always follow the manufacturer’s care instructions for best results.
2. Cold wash only: Use cold water to protect fibers and reduce wear.
3. Skip harsh detergents: Use a gentle soap or mild detergent designed for delicate fabrics.
4. Avoid stretching: Don’t wring out your clothing, as pulling or twisting can weaken the fibers.
5. Air dry: High heat can degrade fibers, so avoid the tumble dryer. 

• Superior sun protection: All our UPF clothing is tested and rated, offering peace of mind.
• Comfort: Lightweight, breathable materials keep you cool while offering exceptional protection.
