Rapha, nice but a bit pricey?

I have been thinking about getting a hi viz too so what better than the rapha brevet gilet. Probably the yellow rather than the pink personally but it would be better having it on than not in the gloomy weather.

Is it a thick material like the softshell gilet?

It's thin. It's a lightweight gilet and not as nice as the ACTUAL lightweight gilet they make.

If you want visibility and a lightweight gilet - just buy a £20 yellow Craft one from Ribble.
