Frequently asked questions

Does the FR33 come in the same sizes in both colours?

Not quite - Grey runs S to 4XL, while Navy runs S to 3XL. If you need 4XL, Grey is the only colour currently stocked in that size.

Is this T-shirt warm enough to wear on its own in winter?

It's rated 'Not Thermal Rated', so it isn't an insulated garment - it's built for flame and arc protection rather than warmth. In cold conditions, wear it as a base layer under FR outerwear.

Can it be worn in wet or damp conditions?

It carries a 'Not Waterproof' rating, so it won't keep you dry in rain. Pair it with waterproof FR outerwear if you're working outdoors in wet weather.

What's the pocket on the chest for?

It's a concealed pocket with a pencil slot, sized for a pen or small tool rather than a phone. There's also a smaller pocket on the sleeve for additional storage.

How much UV protection does the fabric give?

The knit fabric is rated 40+ UPF, blocking around 98% of UV rays - useful for FR work carried out outdoors in direct sun.

What does the IEC 61482 ARC2 rating actually mean?

It's an arc-flash protection classification - ARC2 indicates the garment has been tested and rated for a defined arc-flash energy exposure under IEC 61482, on top of its EN ISO 11612 heat protection.

Can I get my company logo added to this T-shirt?

Yes - both embroidery and logo printing are available on this garment. Speak to our team about placement and setup for your order.
