I bought this as a bit of a trial to add to an all-black motorcycle jacket.
I was a little sceptical at first as the yellow colour has an almost pastel tone and does look a little lighter than other hi-viz materials. The adhesive also seemed a bit weak so I had my doubts that this would work.
Needn't have worried though. My jacket now has strips added across the back, around the tops of the shoulders, down each arm and across the chest.
The tape really stands out against a dark background and is nicely reflective. It also sticks very well and despite the semi-porous textile surface it's stuck to, it's survived several commutes at motorway speeds with just one corner lifting a tiny bit.
Excellent cost effective way to stand out a bit more on the road.
