Hi-Vis Summer Workwear: Staying Visible and Cool
High-visibility clothing is one of the few things on site that can’t be dropped when the weather warms up. The problem is that traditional hi-vis is often the hottest thing a worker owns and in the middle of a Bedfordshire summer, that’s a real issue.
The good news is that staying seen and staying cool aren’t a trade-off any more. Breathable hi-vis has come a long way, and there’s a sensible option for almost every summer task.
Why Visibility Still Matters in Summer
Roadsides, yards, warehouses and busy sites all rely on workers being clearly visible, whatever the season. Bright sun and glare can actually make it harder to pick people out, not easier, so compliant hi-vis stays just as important in July as it is in January.
Managing heat alongside that is part of an employer’s duty of care — the HSE’s guidance on managing workplace temperatures (HSE: Managing workplace temperatures) is a useful reference.
The Heat Problem With Traditional Hi-Vis
A heavy hi-vis jacket or thick waistcoat over a t-shirt traps heat fast. Workers end up uncomfortable, distracted and tempted to take it off, which defeats the point entirely. Comfort and compliance go hand in hand: kit that’s bearable in the heat is kit that actually gets worn.
Breathable Hi-Vis Options
For summer, the most useful pieces are lightweight and air-permeable: hi-vis polos, breathable hi-vis t-shirts and micro-mesh vests that let air move through. They keep a team visible while shedding heat across the day.
Staying Compliant: EN ISO 20471 Classes
Summer hi-vis still needs to meet the right standard for the environment. EN ISO 20471 sets out Class 1, 2 and 3 garments depending on the level of risk and the speed of nearby traffic. Choosing breathable garments that hold the class you actually need means you don’t have to choose between comfort and compliance.
Branding Hi-Vis the Right Way
Hi-vis garments can be branded without compromising their reflective performance, as long as logos are placed correctly and away from the reflective bands. Done properly, your team stays compliant, visible and clearly identifiable as yours.
Layering for Changeable Summer Weather
British summers rarely stay settled. A breathable hi-vis polo as the everyday base, with a lightweight hi-vis jacket on hand for showers or cooler starts, covers most of what a season throws at a team without anyone overheating.

Frequently Asked Questions
Is breathable hi-vis still fully compliant?
Yes, provided the garment carries the EN ISO 20471 class you need. Breathability is about the fabric construction, not a drop in the safety rating.
What's the coolest hi-vis option for summer?
Micro-mesh vests and breathable hi-vis polos tend to be the coolest, as they let air move through the fabric.
Can hi-vis be embroidered or printed?
Yes, as long as branding is placed away from the reflective bands so it doesn’t affect compliance.
