Why Brevet over PT? (I haven't used the Brevet)
It keeps you warmer when you're not moving, which is good if you're like me and get perilously cold the second you stop riding. It stops me from shivering like a whippet at coffee stops. I also like the hi-viz stripes.
Good point, I've got plenty of nature's insulation and generally run a little warmer. Hi-viz stripes can do one though.
