The SST-104 is a hi vis workwear set built for summer site work — a short sleeve hi-vis t-shirt paired with matching hi-vis shorts in a black/yellow colourway that's practical, professional, and EN ISO 20471 certified. When a full fleece tracksuit is too heavy for warm weather but dropping your hi-vis compliance isn't an option, this is the set that closes that gap.
The black body with yellow fluorescent panels keeps the SST-104 looking clean through a full working week, resisting the dirt and grime that shows immediately on all-yellow workwear. Retroreflective tape runs across the chest and back on the t-shirt, and around the lower legs of the shorts — positioned to meet EN ISO 20471 tape requirements. Both pieces are cut from breathable polyester mix that wicks sweat away during physical work and dries quickly between shifts.
Machine washable at 40°C. Hang to dry — do not tumble dry.
For cooler conditions, see our hi-vis fleece tracksuit sets. For hi-vis shorts sold separately, browse our hi-vis workwear shorts. For a smarter summer option, our hi-vis polo shirts work in the same warm-weather conditions.
