Sun Protection

Swim Skins and Sun Protection
We at Swim Skins recognize the increasing importance of protecting our skin from the harmful effects of exposure to the sun’s ultraviolet radiation. All our fabrics are chosen with this in mind and tested according to the Australian Standard:- Sun protective clothing - Evaluation and classification AS/NZS4399: 1996. We only use fabrics that offer Excellent Protection (see table below). Moreover, all our ranges are designed to include coordinating Sun Protective Tops.
 
Ultraviolet Protection Factor
Ultraviolet Protection Factor (UPF) testing involves exposing a fabric to ultraviolet radiation (UVR) and measuring how much is transmitted through the sample. Different wavelengths of radiation in the UVR spectrum have different effects on human skin and this is taken into consideration when calculating the UPF rating.

The UPF shows how well a fabric protects your skin from solar UV and lets the consumer select sun protective clothing with confidence. The table below shows how well the fabrics of various UPF ratings block UV.

 
UPF Rating UV Protection UV Blocked
15, 20 Good Protection 93.3% to 95.8%
25, 30, 35 Very Good Protection 95.9% to 97.5%
40, 45, 50, 50+ Excellent Protection > 97.5%
 
Caveats
The UPF rating is for the fabric and does not address the amount of protection that is afforded by the design of the article. The manipulations involved in garment manufacture such as stretching and sewing might lower the UPF of the material.

The protection offered by a fabric may be lessened: at points where the fabric is in close contact with the skin, such as across the shoulders; if the fabric is stretched; if the fabric is wet; with time due to exposure to effects of cold water.
