Overview

Portwest S491 - Overview

The Portwest S491 is a lightweight waterproof jacket from the Sealtex Ultra collection, built for wet-weather site and highways work where freedom of movement matters as much as staying dry. Welded seams and a breathable, stretch fabric keep the rain out without the stiffness of heavier PVC rainwear.

Frequently asked questions

Is the S491 fully waterproof or just water resistant?

It is fully waterproof, not just resistant. The seams are welded rather than just taped, and the Texpel Splash Eco fabric finish beads water off the surface rather than letting it soak in.

Will I overheat wearing this on an active shift?

The Sealtex Ultra fabric is breathable and windproof with mechanical stretch, so it is designed to move with you and let heat escape, unlike a stiff PVC rain jacket. There is no insulation lining, so it works best as a shell over your own layers.

What sizes does it come in?

Every size from XS to 5XL, in Yellow. Check the size guide against your usual jacket size, as the cut is designed to fit over site clothing.

Does it meet a recognised hi-vis and waterproof standard?

Yes. It is EN ISO 20471 Class 3 for hi-vis and EN 343 Class 3 (20,000mm) for waterproofing, both CE certified and UKCA marked.

Can I get my company logo added?

Yes, embroidery and logo printing are both available on this jacket. Ask about trade-account pricing for company branding.

How long does delivery take?

This jacket is dispatched in 1-2 working days.

Does the hood detach or pack away?

The hood packs away when it is not in use rather than detaching completely, so it stays with the jacket.
