My son was so impressed by my jacket from onestopcopshop, at £18, he wanted one. I tried offering half price, as suggested, but it wasn't accepted. I got a counter-offer of £17.50, so bought it at that.
I can recommend these hi-vis jackets. Mine was almost new, it is warm and light and very, very bright. I've not had chance to try it in the rain yet so don't know how waterproof it is, but it is genuine Goretex.
Do people give me more room? Not too sure about that, but it is amusing seeing sportsbike riders keeping to 30mph from the lights when they would normally hare off at way beyond the speed limit.
