UPF clothing vs. UV protection clothing: what's the difference?

When people talk about sun protection, many immediately think of sunscreen. However, in recent years, UPF clothing (often also called UV-protective clothing) is becoming an increasingly popular solution to protect the skin from ultraviolet rays during outdoor activities and in daily life.

The reality is that not all fabrics offer the same protection. A normal t-shirt can let a significant amount of UV rays pass through, while a UPF-certified garment is specifically designed to reduce skin exposure to UVA and UVB rays.

What is UPF clothing?

UPF stands for Ultraviolet Protection Factor. This value indicates how much ultraviolet radiation can penetrate the fabric and reach the skin.

For example:

  • UPF 15 blocks approximately 93% of UV rays;

  • UPF 30 blocks approximately 96% of UV rays;

  • UPF 50+ blocks at least 98% of UV rays.

In practice, a UPF 50+ fabric allows less than 2% of ultraviolet radiation to pass through.

For this reason, UV-protective clothing is an increasingly important tool in preventing sun damage and protecting the skin.

Normal clothes vs. UV-protective clothes

The main difference is that UPF clothing is designed and tested to offer certified protection from UV rays.

Many traditional garments can provide some shielding, but the level of protection varies significantly based on:

  • fabric composition;

  • color;

  • thickness;

  • weave;

  • wear and tear of the garment.

UV-protective clothing, on the other hand, is developed with specific materials and processes that allow it to maintain high protection even during prolonged use.

SPF sun protection vs. UPF protection: what are the differences?

One of the most frequent questions concerns the difference between SPF and UPF.

SPF

SPF (Sun Protection Factor) measures the ability of a sunscreen to protect against UVB rays, which are responsible for sunburn.

Its effectiveness depends on:

  • amount applied;

  • correct distribution on the skin;

  • frequency of reapplication;

  • contact with water and sweat.

UPF

UPF, on the other hand, measures the ability of a fabric to block both UVA and UVB rays.

The main advantage is that the protection is integrated directly into the garment and does not require reapplication throughout the day.

For this reason, the most effective approach is to combine SPF 50+ sunscreen and UPF clothing.

Why choose lightweight and breathable UPF clothing

When thinking of protective clothing, one often imagines heavy and uncomfortable fabrics. In reality, modern textile technology makes it possible to obtain high UV protection while maintaining lightness, breathability, and comfort.

nule's UV-protective clothing offers UPF 50+ protection, blocking at least 98% of UV rays, but it has also been designed to be lightweight, cool on the skin, and quick-drying.

This allows the garments to be used even on the hottest days or during outdoor activities without compromising comfort.

When to use UPF clothing

UV-protective clothing is particularly useful during:

  • sun walks;

  • trekking;

  • running;

  • cycling;

  • beach days;

  • travel;

  • reading in the park;

  • daily outdoor activities.

Especially when the UV index is high, protecting the skin with a physical barrier can significantly reduce exposure to ultraviolet rays.

Which garments to choose?

The choice depends on the type of activity and the desired level of coverage.

For those looking for versatile everyday protection, garments like the Crio Top, the Crio T-shirt, or the Cooling T-shirt by nule allow easy integration of UV protection into daily routines.

Made with selected and certified technical fabrics, they are designed to offer protection, lightness, and practicality without sacrificing style.

How does UPF technology work in nule fabrics?

When UPF protection is integrated directly into the fabric, as in the case of nule garments, the fibers are designed and processed to offer effective shielding against UV rays.

This means that the protection does not come from a simple surface treatment but is part of the fabric's inherent characteristics.

The result is a garment designed to accompany you during daily activities, offering constant protection from UVA and UVB rays.

Conclusion

UPF clothing, also known as UV-protective clothing, represents one of the most effective solutions today for improving sun protection. Used in conjunction with SPF 50+ sunscreen, it helps protect the skin from UVA and UVB rays and reduce the risk of long-term sun damage. Choosing lightweight, breathable, and UPF 50+ certified garments, such as those developed by nule, allows for easy and comfortable integration of photoprotection into daily life.
