Blackrock hi-vis vest – yellow (size S)
Want to be seen without any faff? The Blackrock hi‑vis vest does exactly what it should: bright fluorescent yellow fabric with retro‑reflective tape so you’re visible in daylight, twilight and after dark. It’s a straightforward, practical bit of kit that keeps you noticed and safe — whether you’re on a building site, doing roadside repairs, working security or cycling home in poor light.
Practical details
Cut from soft yet hard‑wearing polyester, the vest is lightweight and comfortable enough for long shifts. The black edge trim hides scuffs and dirt, so it looks smarter for longer — handy when there’s no time for a full wash. The front uses a hook‑and‑loop fastening (Velcro) for quick on and off, which is a proper bonus if you’re in a rush or need to nip off for a break.
Key features
- Fluorescent yellow fabric with two horizontal bands and two shoulder braces of retro‑reflective tape — boosts visibility at distance and under headlights.
- EN ISO 20471 certified — tested to recognised hi‑vis safety standards for peace of mind on site.
- Lightweight polyester construction for comfort and freedom of movement during work or cycling.
- Sleeveless design lets you layer underneath and keeps arms free for manual tasks.
- Hook‑and‑loop fastening for ease of use, even with gloves on.
- Black trim reduces obvious dirt and helps the vest keep a tidy appearance.
Who is this for?
- Construction and maintenance crews needing clear visibility around machinery and vehicles.
- Security staff, event marshals and stewards who must be easily identified.
- Cyclists and couriers after a simple, packable visibility option for early starts or late finishes.
- Anyone working roadside, on sites, or in car parks where being seen really matters.
Worried it might feel heavy after a full day? This vest stays light and doesn’t restrict movement, so there’s no awkward bulk under a jacket. This listing is for size S in yellow; the style is available across a wider size range. Certified by UK‑approved testing to EN ISO 20471, it gives that extra layer of confidence when you’re near traffic or working in low light. If you’re unsure about sizing or how it sits over specific outer layers, it’s sensible to try it on over what you’d normally wear on the job.
All in all, it’s a no‑nonsense, dependable hi‑vis vest that does the job: keeps you seen, keeps you safe, and doesn’t get in the way.
