I used to grab whatever old t-shirt was clean. By mile one I was soaked and freezing by mile three. These actually wick and dry fast enough to keep up with you.
















Too warm for a real jacket, too cold for just a long sleeve. This in-between temperature wrecked me until I found layers I could strip off mid-run without carrying a backpack.
















Shorts at 40 degrees? No. Full thermal tights? I'm drenched by mile three. Finding the right bottoms for cool mornings took me way too long.
















Lost feeling in my hands during a December run once and couldn't even unlock my phone after. Never again. These small pieces make the biggest difference below 45 degrees.













Stepped in a puddle at 5:50am in cotton socks once. Spent the next four miles with frozen toes. That was the morning I finally took cold-weather socks and grip seriously.
