While choosing your clothes for a cold run might seem easy, the material, number of layers and amount of time you plan on spending outside all matter significantly. Additionally, understanding your own temperature baselines—are you someone who tends to run cold?—will determine what you wear to start each run.
In cold weather (45-55 degrees), Brenner recommends people wear pants or tights and a long sleeve shirt. For some, this weather is still balmy enough to get away with capris or shorts. Gloves can be helpful, though not always necessary on shorter runs.
In colder weather (25-45 degrees), tights or pants, a long sleeve shirt and a warm vest or windproof jacket is a smart choice. Gloves or mittens work well for most here. For added warmth, opt for fleece-lined wool mittens.
In coldest weather, when temperatures drop below 25°F, wearing insulating base layers is vital. Windproof or fleece lined tights are great options, as are wool long sleeve shirts and jackets. Mittens are a must, and pairing them with glove liners can add extra protection against the chill.
