UPF & Swimwear

What is it, how it works and why it is so important.

You may have read on UBU Swimwear product descriptions or noticed me mentioning that UBU Swimwear has a UPF 50+ rating. But what does that mean? Read on to find out!


What is UPF?

UPF (Ultraviolet Protection Factor) indicates how much UV radiation the fabric allows to reach your skin. The fabric used for UBU Swimwear has a rating of UPF 50+ - the highest rating possible.  This means it allows only 1/50th of the sun's UV radiation to pass through - ie the fabric will reduce your skin's UV radiation exposure by 50 times in areas where the skin is protected by the fabric. That's like a UV block of 98%.


Difference between SPF and UPF?

Both SPF (Sun Protection Factor) and UPF (Ultraviolet Protection Factor) are standards used to measure sunburn protection. SPF is the standard used to measure the effectiveness of sunscreens & only measures UVB, whereas UPF is a standard for measuring sun protective fabrics and measures both UVB and UVA. 

UVB is responsible for much of the skin damage caused by sunlight, especially sunburn, but UVA plays an important factor in other types of sun damage, including premature aging, wrinkles and the development of skin cancers. Hence why protection from both UVA and UVB is important.



Not all swimwear offers sun protection. In fact, most swimwear offers UPF rating of 15. A rating of at least 30 is needed for adequate sun protection.
UBU Swimwear is made using a luxury Italian fabric called Carvico Vita. This fabric has a UPF rating of 50+. This is the highest possible rating and offers excellent sun protection.

UPF is also another reason why your swimwear care routines are super important. Looking after your swimwear properly will make sure the fabric stays at its best, offering the highest sun protection possible for as long as possible. Read more about caring for your swimwear here.


☀️Protect your skin

  • If you are out and out in the sun, clothing offers the best protection. UPF protection from clothing is consistent over time and doesn’t wear off like sunscreen does.
  • But clothing also leaves some skin exposed, so sunscreen is a must too! And don’t forget your hands! 

Did you know? 👇

Dark or bright colours keep UV rays from reaching your skin by absorbing them rather than allowing them to penetrate, providing better protecting than lighter colours. If there's a light coloured swimsuit and darker coloured suit both rated UPF 50+, the darker coloured suit will be better at protecting during water-based activities, fabric stretching and normal wear and tear on the fabric.
