Hi-vis workwear in winter: staying safe and seen

Dark mornings, early sunsets, rain, ice, and fog. Winter comes with a whole new set of challenges if you work outdoors.

Not only do you need hi-vis workwear that can help you be seen despite reduced visibility. But, you’ll also need it to be warm and durable enough to keep you toasty throughout those chilly winter days.

Here’s all you need to know about choosing the right hi-vis workwear for winter.

What are the key considerations when choosing high-visibility winter workwear?

There are two main considerations to keep in mind when choosing hi-vis workwear for winter:

1. VISIBILITY IN LOW-LIGHT CONDITIONS

High-visibility workwear is designed to boost your visibility at work. But it will need to work even harder in winter.

This is because winter comes with reduced daylight hours, as well as harsh weather that could make it harder for you to be seen, like fog and heavy rain.

2. PROTECTION FROM HARSH WEATHER

Your hi-vis workwear will need to keep you warm, comfortable and dry in extreme winter weather.

You’ll need it to be warm and durable enough to withstand low temperatures, as well as wind, rain, and even snow.

What to look for in a hi-vis winter jacket

Hi-vis coats and jackets need to keep teams warm, dry, and clearly visible.

HSE guidance states PPE must be suitable for the environment, conditions, and task, while allowing wearers to work safely and comfortably throughout the day.

Key features to consider include:

1. INSULATION

Good insulation helps teams maintain body temperature during cold conditions, especially when working outdoors for long periods.

HSE advises that PPE should protect against foreseeable weather risks, including prolonged exposure to cold. Thermal linings or advanced synthetic insulation provide warmth without unnecessary bulk.

2. WEATHERPROOFING

Protection from rain and wind is essential in winter. Jackets should be water-resistant or fully waterproof, with features such as high collars, adjustable cuffs, and storm flaps to reduce heat loss.

 

3. BREATHABILITY

Moisture build-up can quickly lead to discomfort once activity levels change. Breathable fabrics and moisture-wicking linings help regulate temperature by allowing heat and sweat to escape.

4. VISIBILITY

Hi-vis winter workwear must comply with EN ISO 20471, ensuring workers are visible in daylight, low light, and night-time conditions. HSE guidance requires employers to assess visibility risks and select the correct class accordingly.

During winter, reduced daylight and poor weather may mean higher visibility classes are required.

5. VERSATILITY

Weather conditions can change quickly.

HSE encourages PPE that remains suitable across varying conditions, reducing the need for frequent changes. Layered or 3-in-1 jackets allow teams to adapt without compromising protection.

6. DURABILITY 

Outer fabrics should withstand abrasion, repeated use, and harsh conditions. Durable materials help ensure jackets remain effective over time. 

Abrasion-resistant outer fabrics help jackets withstand harsh environments and repeated use.

 

7. COMFORT AND MOVEMENT

Workwear should support movement, not restrict it. Lightweight insulation, articulated sleeves, and stretch panels help teams work safely and comfortably.

 

8. FIT

A correct fit is essential for performance and protection. Jackets should allow room for base and mid-layers while remaining secure during movement.

Other hi-vis workwear to consider for winter

A layered approach supports warmth, comfort, and visibility.

HSE recommends considering the full range of PPE required for cold environments, not just outer layers.

HI-VIS WORK TROUSERS FOR WINTER

Winter hi-vis trousers should provide insulation, weather resistance, and durability to protect against cold and wet conditions.

HI-VIS BIB AND BRACE TROUSERS FOR WINTER

High-visibility bib and brace trousers offer increased coverage and help reduce heat loss around the lower back and core.

HI-VIS WINTER FOOTWEAR

Hi-vis safety boots should be insulated, waterproof, and slip-resistant. HSE advises selecting footwear suitable for weather conditions and surface risks.

Non-metallic safety toes can also help reduce cold transfer.

What safety standards does my hi-vis winter workwear need to meet?

All hi-vis clothing must meet the EN ISO 20471 standard, which defines minimum visibility requirements.

HSE requires PPE to meet relevant standards and be selected following a suitable risk assessment.

The three visibility classes are:

• Class 1 - lower-risk environments such as warehouses and delivery yards
• Class 2 - medium-risk environments
• Class 3 - higher-risk environments, including highways, rail, and night work

During winter, reduced daylight, poor weather, and longer periods of darkness may increase visibility risks.

Reviewing PPE requirements in line with HSE guidance helps ensure teams remain protected throughout winter conditions.
