The SST-103 is a hi vis t-shirt and shorts set for construction and outdoor site workers who need EN ISO 20471 compliant workwear through the UK summer months. Yellow/black two-tone colourway — the standard for general construction, warehouse, logistics, and facilities environments. Short sleeve top and matching shorts, both certified, both machine washable at 40°C.
Where the SST-104 uses a black base with yellow panels, the SST-103 leads with the yellow fluorescent body — more surface area of fluorescent fabric means stronger daytime visibility, which matters on open sites, roadsides, and anywhere you're working alongside moving vehicles or plant machinery. The retroreflective tape on the t-shirt runs across the chest and back. Both garments are cut from breathable polyester mix that pulls moisture away from the skin and dries fast between shifts — built for five-day-a-week outdoor use, not just occasional wear.
Also available in orange/black (SST-103 multi-colourway). For colder months, the hi-vis fleece tracksuit sets cover the same compliance requirement in heavier fabric. For hi-vis shorts without the top, browse our hi-vis workwear shorts.
