Frequently asked questions

What's the difference between Class 1 and Class 2 hi-vis?

Class 1 provides less background reflective material than Class 2, so it suits lower-risk sites away from fast-moving traffic. Check your site's risk assessment before choosing this over a Class 2 or 3 garment.

Is this polo suitable for hot weather?

Yes. The Ezeecool fabric is designed to wick moisture and keep the wearer cool, and the quarter-zip collar can be opened for extra ventilation.

What sizes are available in each colour?

Both Orange/Black and Yellow/Black run the full range from S to 6XL.

Can I clip a radio to it?

Yes, it has a dedicated radio loop for hands-free clipping.

Can I add my company logo?

Yes, embroidery and printed logo branding are both available to order.

How long does the hi-vis certification last?

The garment is certified to EN ISO 20471 after 50 washes, so following the wash-care label keeps it within certification.

What's the current lead time?

1-2 working days from order, based on current stock, across all sizes and colours.
