When you live under the harsh New Zealand sun, protecting your skin is a daily essential — not just a summer concern. While sunscreen is crucial, your clothing is your first line of defence against UV exposure.
That’s where UPF clothing comes in. Designed to block harmful ultraviolet rays, UPF clothing keeps you safe and comfortable through all your adventures — from the coast to the mountains.

What Is UPF Clothing?
UPF (Ultraviolet Protection Factor) measures how well a fabric shields your skin from the sun’s UV rays. Just like SPF for sunscreen, a higher UPF rating means stronger protection. UPF 50+ blocks around 98% of UV rays, allowing only 2% to reach your skin. A standard cotton tee, by comparison, only offers about UPF 5, leaving you exposed to sun damage.
How Does UPF Clothing Work?
UPF clothing works thanks to advanced fabric construction and materials—denser weaves, unique fibres, 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 defence against harmful UV exposure.
How Long Does UPF Clothing Last?
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.
Does UPF Wash Out?
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.
Why UPF Clothing Is Essential in New Zealand
New Zealand’s UV index regularly ranks among the highest in the world — even on cloudy days. That means sun protection isn’t optional; it’s vital.
Wear UPF 50 clothing whenever you’re:
-Out on the beach or boat, where sun reflects off sand and water.
-Exploring high-altitude tracks, where UV intensity increases.
-Spending everyday time outdoors, from walking the dog to weekend sports.
Pro tip: Look for moisture-wicking UPF clothing to stay cool and dry during long, hot days.
Do You Still Need Sunscreen?
Yes. UPF 50 clothing offers excellent coverage, but areas like your face, neck, and hands still need broad-spectrum SPF 50+ sunscreen. Combine both for complete sun protection — especially during peak UV hours (10 am – 3 pm).
Does Colour Affect UPF Protection?
In standard fabrics, darker colours usually block more UV rays. But with Helly Hansen UPF clothing, every piece is independently tested to ensure consistent protection — no matter the colour
UPF 50 Clothing vs Regular Clothing
While all fabrics offer some level of UV resistance, most everyday clothes can’t compare to certified UPF 50 apparel. Regular shirts or light cotton garments often allow too much UV radiation through, particularly when wet.
That’s why Helly Hansen’s UPF 50 shirts and tops are engineered to perform — offering reliable, long-lasting protection for the New Zealand outdoors.
How To Wash UPF Clothing
Like all garments, UPF clothing should be cared for in the right way to maintain its effectiveness.
Read the label: Always follow the manufacturer’s care instructions for best results.
Cold wash only: Use cold water to protect fibres and reduce wear.
Skip harsh detergents: Use a gentle soap or mild detergent designed for delicate fabrics.
Avoid stretching: Don’t wring out your clothing, as pulling or twisting can weaken the fibres.
Air dry: High heat can degrade fibres, so avoid the tumble dryer.
