Three finishes for people who work in the sun.
UPF 50+ blocks the UV. Coolant keeps the wearer up to 3°C cooler. Fade-free keeps the colour. Here's how each one works.

Ultraviolet Protection Factor 50+ means the fabric lets through less than 2% of UV radiation. It's a rating on the fabric, tested — not a claim about the colour or thickness.
A herbal cooling treatment applied to the fabric that increases moisture absorption and drying, keeping the wearer up to 3°C cooler than the same untreated fabric.
A dye-lock treatment that binds the colour into the fibre so blacks stay black and brand colours stay true through sun and repeated washing.
When to specify them
Delivery riders, field sales, security, event crew and sports teams. Anyone outdoors for hours gets all three; anyone who washes daily gets fade-free at minimum.
