Why it works

Active fit, flexible reflective tape

Radio loop

A shoulder-mounted radio loop keeps a radio clipped on and within reach.

Cooling, moisture-wicking fabric

Premium cooling fabric wicks moisture to keep the wearer dry through an active shift.

Segmented Hivistex Pro tape

Heat-applied segmented reflective tape stays flexible without restricting movement.

40+ UPF sun protection

Rated 40+ UPF, blocking 98% of UV rays for outdoor work.

RIS 3279-TOM rail compliant

The Orange/Black colourway meets RIS 3279-TOM, so it's cleared for rail trackside work.

Frequently asked questions

What does DX4 mean?

DX4 is Portwest's active-fit hi-vis range, built with premium cooling fabric and a sportier two-tone design rather than a standard boxy hi-vis cut.

Is the reflective tape flexible?

Yes - it's heat-applied segmented Hivistex Pro tape, designed to flex with movement rather than a single rigid strip.

Does it have a radio loop?

Yes, there's a shoulder-mounted radio loop for clipping on a radio.

Can I wear this on rail sites?

Yes, but only in Orange/Black - that colourway meets RIS 3279-TOM for rail industry work. Yellow/Black is EN ISO 20471 Class 2 only.

What sizes are available?

S through to 6XL, in both Orange/Black and Yellow/Black, unisex active fit.

Can I get this branded for my company?

Yes - both logo printing and embroidery are available, and the two-tone panel design suits corporate or branded workwear.

Is it waterproof or thermal rated?

No - it's a lightweight long-sleeve T-shirt with no waterproof or thermal rating, designed for hi-vis visibility rather than wet or cold-weather protection.
