I stumbled across a question on whether yellow or orange safety vests were better for visibility, and it got me wondering - I have a vest that consists only of the silvery reflective fabric (and it definitely is reflective, I cannot pass a disinfectant dispenser without it going off from some meters away...). Now, I haven't seen any other cyclists wearing one of these, so I can't quite judge the visual impact - is it fine, or do I suddenly go from "barely visible" to "sudden (too) bright spot" in a way that is unsafe when a car's lights hit the vest?

I think your main problem will be when it’s not dark.

I’ve noticed with my Castelli Gabba jersey which is a really bright fluorescent yellow that people notice me much earlier at intersections or when they only quickly glance over their shoulder. The effect is especially noticeable on those rainy, foggy days in fall but of course requires some daylight or at least streetlamps. In ambient lighting silvery reflective fabric looks pretty close to stealthy gray.

At night I think proper lights and maybe good spoke reflectors (the yellow plastic kind) are much more important. The problem with reflectors is that they are unreliable. They only work if the other road user has a working headlamp which is close to their eyes (retro-reflectors reflect light straight back at the source, that’s why they work so well) and aimed in your direction. I consider front and rear reflectors a bad back-up in case your normal lights fail at the worst possible moment or without you noticing.

Large reflector surfaces can be dazzling, especially for car drivers using their high beams. So this could be a concern with a jacket which is one big reflector. But then again … road signs are usually much bigger and more reflective than reflective fabric or tape and their dazzling effect is bearable.

    As a driver, I greatly prefer riders with reflective vests to either lights or on-bicycle reflectors. They're much easier to spot and track. (Blinking lights are my least favorite: I might be able to see that there's a bicycle somewhere ahead of me from a half-mile away, but I might not figure out where until just before I swerve to avoid a collision.)

    Swerving to avoid a hazard you can't pinpoint seems like a dangerous mistake, to me. Why would you do that instead of slowing down and scanning more carefully?

  • I've just bought an all-reflective jacket and found the same. And and this time of year one commute can be pitch dark, the other drizzly and dimly lit - just enough light that some cars don't have their lights on

  • When wet, the silvery stuff tends to be no longer reflective. They are made of tiny hemispheric lenses on silvery underlying material. Water fills the 'valleys' and the lens-effect is thus annihilated.

    @Bicifriend, because I'd just pinpointed the hazard as being twenty feet ahead of me rather than the quarter-mile away I'd thought it was. Wearing black clothing and riding a black bicycle at night may look rather stylish, but it's also nearly impossible to see from any distance, and a blinking red light doesn't give any useful distance cues.

I can now contribute with some anecdata of my own: today a colleague commented how easy it was to see me in my reflective vest when driving. (This was in rainy weather on a semi-dark morning, so I guess the loss of reflectivity can’t have been too bad.)
