What fabrics are best?
Fabrics do not need to be UPF rated to provide
protection. Try to choose fabric
structures,
colours and other characteristics that increase
protection.
Fabric structure
The tighter the fabric
structure, whether knitted
or woven, the better the sun protection.

As the
fibres of tightly woven fabrics are closer
together, less UV radiation is
able to pass
through to the skin. Tightly woven, lightweight
natural fabrics such as linen, cotton or hemp
will also help keep you cooler than synthetic
fibre equivalents.
Tension
If a fabric
is stretched, it will be less protective.
This is common in knitted or elasticised fabrics.
Take care to select the correct size for the
wearer or if wearing stretchy fabrics choose
fabric structures and colours
that provide
greater protection to offset the effect of the
stretch.
Layering
Layering of fabrics and garments is an effective
way to increase protection from UV.
Colour
Many dyes absorb UV radiation. Darker colours
(black, navy and dark red) of the same fabric
type will absorb more UV radiation than light
pastel shades (white, sky blue and light green).

Choose darker colours where possible. If you
want to choose a light-coloured fabric, other
choices such as fabric
structure will become
more important.
