UV Protection

Blocks the ultraviolet radiation that would otherwise pass through the cloth to the skin. A typical lightweight summer shirt protects far less than most people assume; what actually works is a tight construction in fibres that absorb UV in their own right

How it works

Stop what gets through

Ultraviolet light reaches the skin two ways: straight through the gaps between yarns, or through the fibres themselves — so protection comes by two routes. Polyester absorbs ultraviolet by its own molecular structure, with the protection built into the material; nylon-based fabrics carry a UV absorber applied as a finish instead. Either route still needs a dense construction to close the gaps between yarns. Deeper shades and higher density both help; stretching and wetting both reduce protection, which is worth noting for close-fitting styles.

Performance Profile

Evidence-led proof points explain what this material technology delivers. Values depend on construction and verified testing.

01 UV Protection

UV Protection

UV protection comes from one of two sources. Polyester absorbs ultraviolet light by its own molecular structure, so the protection is built into the material and does not fade with laundering. Nylon-based fabrics carry a UV absorber applied as a finish — equally effective, but wash durability depends on how the finish is specified. This is the question brands actually ask: whether a sun-protective garment still works after a season, and the answer depends on which route it takes

02 Dense Construction

Dense Construction

The easiest path for ultraviolet light is straight through the gaps between yarns. A dense plain weave or piqué knit closes those gaps so there is no clear route through, while the polyester itself absorbs UV by its molecular structure — it takes both to give real protection. Worth knowing: stretching or wetting the fabric opens those gaps, so a close-fitting garment protects somewhat less than the flat fabric measures
