1–5 business daysFor professional use, hi-vis coveralls typically need to comply with the EN ISO 20471 standard, which classifies high-visibility clothing into three classes based on the area of visible background material and reflective tape. Class 3 offers the highest level of visibility and is often required for high-risk environments like road construction or airport operations. Always check your specific workplace safety requirements to select the correct class.
Yes, manufacturers offer distinct options for different seasons. Lightweight unlined coveralls are designed for warmer weather or indoor work, focusing on breathability and moisture management. For cold environments, you should look for winter hi-vis coveralls that feature thermal insulation, often with quilted linings and windproof outer layers, to maintain body temperature without compromising visibility.
You must follow the manufacturer's care label instructions strictly, as improper washing can degrade the reflective properties and the fluorescent colour. Generally, these garments should be washed inside out at maximum temperatures of 40°C or 60°C, using mild detergents without optical brighteners or bleach. Avoid tumble drying unless the label permits it, as high heat can damage the reflective tapes.
A full coverall is a one-piece garment that covers the entire body, offering maximum protection against dirt and hazards while providing the highest potential visibility surface area. A bib and brace, often called a dungaree, covers the legs and torso but leaves the arms and shoulders exposed. Bibs allow for greater freedom of movement and airflow but usually require a separate hi-vis jacket or t-shirt to meet higher safety class requirements.
Most professional-grade hi-vis coveralls are equipped with dedicated knee pad pockets designed to hold protective inserts. These pockets are reinforced to withstand abrasion from kneeling on rough surfaces like concrete or grating. Using knee pads significantly improves comfort and prevents long-term joint injuries for workers in construction and maintenance sectors.
While both colours are EN ISO 20471 compliant, the choice often depends on the specific industry regulations. Hi-vis orange is typically mandated in the rail industry (RIS-3279-TOM standard) to ensure contrast against green vegetation and stone ballast. Hi-vis yellow is widely used in construction, warehousing, and general roadworks, as it provides excellent luminosity in low-light conditions.
Ensuring your team is equipped with the correct safety gear is crucial for operational efficiency and compliance. We invite you to explore our comprehensive selection of coveralls to find the perfect solution for your specific work environment.
