Frequently asked questions

Is the F438 Iona coat fully waterproof?

Yes. It's rated to EN 343 Class 3, the highest waterproof class in the standard, with taped seams and a PFAS-free Texpel Splash Eco finish that beads water off the fabric surface.

What sizes and colours are available?

The Iona coat comes in Navy only, in sizes S through to 4XL.

Does it have any visibility features?

Reflective tape runs across the chest, waist and hem, adding visibility in low light without being a high-visibility garment.

Will it keep me warm as well as dry?

No, this coat isn't thermally rated, so it's built for waterproofing rather than warmth. Layer underneath in cold conditions.

How many pockets does it have?

Two lower pockets, both accessed through the front zip opening.

Is the coat fitted or a looser cut?

It's a unisex, longer-length cut designed to go over other workwear, with elasticated inner cuffs and an adjustable hood for a secure fit.

Can this coat be customised with a logo?

No, embroidery and logo printing aren't available on this style.
