Getting outside for fresh air and exercise is going to be crucial to your mental health as the days get shorter and darker. Luckily, the cold weather doesn't need to stop you. A warm coat is a must, but the base layers you're wearing underneath when you're walking, hiking, or working out make all the difference when it comes to staying comfortable for extended periods of time.

When choosing the best base layers for outdoor activities, consider long-sleeve tops that won't make you feel overheated, sweatshirts so soft you'll never want to take them off, and tights that fit comfortably under your favorite pair of jeans. Whether you find yourself hiking in the woods or dining outdoors in December, these base layers are what you need to stay warm.
