10 Cold-Weather Running Must Haves — According to Experts

Nike Therma Running Neck Warmer ($30)

"This is a great article that feels lightweight but still gets the job done," Lauder-Dykes says. "It's toasty without feeling overbearing." It's a highly-rated product on Amazon and many reviewers say it's easy to cover both the nose and mouth with a nice, breathable fit. "Other gaiters I tried were either too thick for breathing while running, or too thin to provide enough warmth or stay in place. This was my go-to gaiter for running in below freezing temps this winter," a fellow customer wrote.
