Every single layer makes you highly visible at night

Any of the four pieces of our Black Light gear can be worn on their own, or as part of the Black Light layering system. The idea for the range is simple. We want to get rid of the outdated idea that you have to add on a specific layer like a high vis vest or jacket to be seen at night. So we designed a high visibility range where every layer, whether it’s a t shirt or a shell, does exactly the same amazing job of making sure you’re seen at night.

It looks completely stealth during the day

By day the midlayer is the same subtle blend of matt black hues as a stealth bomber. We wanted it to look cool, unobtrusive, and not like you’re wearing high vis gear at all. So everything is matt black, from the Swiss materials to the waterproof zip and black glass dots. While the reflective dots kick into life when you shine light at them at night, the rest of the time you won’t really notice them as they’re flush to the material and have a matt, rubberised finish.

How we use black glass to emit light

Most high vis gear uses ugly thick silver reflective tapes or stripes. Ours doesn’t. We’ve custom-made thousands of super-thin matt black dots that reflect light back at any source. The science behind them is simple. Each dot has over 60,000 microscopic black glass spheres embedded in its surface. You can’t see or feel the glass though. Each dot is soft, flat, flexible, completely smooth to the touch and weighs a fraction of a gram.

Reflective dots transform it at night

The midlayer remains matt black at night until light falls on it. Whether it’s car headlights, a torch or a helicopter search light, the midlayer’s 18 reflective dots transform from matt black into glowing discs of bright white light. The dots are all positioned on the parts of your body that move the most – like your elbows, wrists, shoulders and hips – so that when they light up they create a pattern that’s instantly recognisable as a person from any angle.

8 dots of light is all you need to see a person

Colour is useless in the dark as our eyes can’t see it. Instead our brain’s ‘pattern recognition system’ takes over. So we’ve designed our pattern of dots based on the science of seeing someone at night. Experimental psychologists have shown how just 8 dots of light surrounded by complete darkness are all the information our eyes and brain need to understand we’re actually looking at a person. Our brains are so good at it, that in 0.25 of a second we can predict what they’re doing, where they’re going and how fast.

Regulates your temperature through the night

The Black Light Midlayer is built from a single layer of high-performance material made by the high-tech Swiss fabric mill Schoeller. Next to your skin you’ll find a high-wicking soft brushed fleece that’s incredibly breathable. This combination keeps you warm while rapidly getting rid of sweat, making it phenomenal for heat retention and temperature control – exactly what you need as the temperature drops through the night.

Soft and stretchy, it's the opposite of most high vis gear

We wanted to make it the exact opposite of heavy and crinkly high vis gear. So not only is the inside a super soft brushed fleece, but the outside face is just as soft to the touch and quiet while you’re doing sport. Every square centimetre of the midlayer is designed to stretch and never restrict you. The Swiss material has 4 way stretch throughout. And every seam is made using Active Stitch technology at our high-tech factory in Portugal, which means even the seams stretch too.

Wear the system in 14 different combinations

When it comes to sport, you shouldn’t have to make a choice between over-heating and being seen. Whether you’re layering up or stripping off, the Black Light system can be worn in 14 different combinations, and gives you the same high visibility protection at all times. Whatever you’re doing, however fast you’re going, and almost whatever angle you’re seen from, we’ve designed the Black Light system so that at least 8 reflective dots will always be visible.
