Lab-Tested UV Protection.
Measured, not promised.
The fabric of our umbrellas is independently tested to the European standard EN 13758-1. The result: UPF 50+, the highest protection class for textiles.
UPF 400+
Even wet
Even soaked, far above the UPF 50 the standard requires.
7 of 7
Colors passed
Every color variant was measured individually in an independent lab.
Our test results
UPF 50+ is the highest value the standard allows on a label. We measured far more, dry and wet:
* Measured UPF (dry): per EN 13758-1 on the dry main fabric. ** UPF tested wet: per AATCC TM183 on the soaked main fabric.

- Result
- UPF 50 requirement passed in every single test
- Test reports
- No. RTS25R51274TX to RTS25R51287TX. On request, we will gladly send you the test report for your color.

For context: even the lowest measured value means that less than 0.25 % of effective UV radiation passes through the fabric.
What does UPF 50+ mean?
UPF stands for Ultraviolet Protection Factor. It is the textile counterpart to the SPF of your sunscreen: a fabric with UPF 50 lets only one fiftieth of UV radiation through, less than 2 percent. UPF 50+ is the highest rating a textile may carry under the standard.
The difference to sunscreen: an umbrella works instantly, never needs reapplying, and protects exactly where creaming up is a hassle. Hands, hairline, neckline.
UV-B radiation
Causes sunburn and cell damage. In every test, Sunbarry fabrics block at least 99.7 % of UV-B radiation.
UV-A radiation
Penetrates deeper into the skin and ages it prematurely. Here too: over 97 % blocked in every single measurement.
Why the lab test matters so much to me
Hi there,
before Sunbarry existed, I spent a long time looking for a beautiful UV umbrella myself. Something struck me: many umbrellas are advertised with UV protection, but during my research I almost never got to see an independent test report.
So one thing was clear to me from the start: I have our fabrics tested independently in a lab, and I publish the results openly right here for you. You should be able to rely on the protection, not on an advertising promise.
Warm wishes
Common questions about UV protection
Can I use the umbrella in the rain?
Can I use the umbrella in the rain?
Yes. The umbrella is made for sun and rain: the coated fabric is finished waterproof, and the UV protection sits in the weave itself, so rain does not wash it away.
Does the UV protection wear off over time?
Does the UV protection wear off over time?
The protection sits in the densely woven, coated fabric itself, not in a finish that washes out. With normal use, the protective effect remains. Only visible damage to the fabric, such as tears or abraded spots, can reduce protection in those places.
How do I care for the umbrella?
How do I care for the umbrella?
Let it dry open after rain before folding it up, and clean the fabric only with a damp cloth.
Isn't regular clothing enough?
Isn't regular clothing enough?
Often not. A white cotton shirt typically has only UPF 5 to 10, even less when wet. We explain why in our guide: UPF in textiles: why regular clothing does not protect you enough.
Is the umbrella alone enough sun protection?
Is the umbrella alone enough sun protection?
For on the go and spontaneous moments in the sun: yes. Keep in mind, though, that UV light also reflects off water, sand, and bright surfaces and reaches your skin even in the shade. For long days in blazing sun, combine the umbrella with sunscreen on exposed skin and sunglasses.
Can I see the test reports?

Yes. Send us a short message via the contact page telling us which color you are interested in, and we will send you the full test report with its report number.
