I plan to run during the winter months as weather permits. I have a Brooks Nightlife Run Esstenial Jacket, some mid-heavier 1/2 shirts(New Balance NBx Windblock), plus alot of cycling clothes. Like for cycling I generally prefer a vest. You seasoned runners, do you think a vest would work during the colder temps, say down to 30 degrees(F) - I'm in Michigan? Any other tips for winter running? Thank you
