Oooooooooh hi-viz, i said this would become the new helmet debate!!!
Have a read of this test. Very very interesting read.
In test situations, in darkness with a mix of drivers, cyclists where placed on the road side wearing the following clothing in 4 different situations; a black tracksuit, a black tracksuit with fluorescent yellow cycling vest (No reflective materials), a black tracksuit plus a fluorescent yellow cycling vest that includes silver reflective material and a black tracksuit and vest with reflective materials along with 50mm wide silver reflective strips positioned on the cyclists ankles and knees.
The results are very interesting, only 2% of the cyclists that wore just black where identified, 15% of the cyclists that wore a fluorescent vest where identified, 50% of the cyclists that wore the vest with reflective material where identified and a staggering 90% of cyclists that wore everything with reflective leg tape where identified.
The reflective vest they used in this test was similar to this.
How many cycling 'hi-viz' jackets are like this?
Not many!
Things like the Hump backpack cover are good, as they have 2 big strips of reflective tape but, as the study shows, the best place to have reflective tape is on your legs, this is where the vehicles lights are going to be pointing and thats a part of you that should be moving constantly and thus makes it eye catching.
If you wear something like the above, then thats good. 50% of drivers will see you because of that. If you have some longs with good reflective patches all around (i have seen people with these and they are great!) then 90% of drivers will see you because of that.
But this
is not as good as the vest shown above, and this is the most popular thing you will see cyclists wearing when they are trying to be seen. Save your £60, and buy either a vest and some decent lights, or some decent lights!!
