A thermal layer can come in a variety of forms, from a heavyweight half-zip shirt to a cushy microfleece pullover. This layer should be made of synthetic or wool fabrics (avoid cotton) to continue the moisture-wicking process started at the base layer.
The plush, semifitted Asics Thermopolis Lite Crew is surprisingly warm for a lightweight long-sleeve shirt, making it perfect for chilly morning runs. The top's soft and stretchy polyester/lycra fabric also excels at moisture management and breathability; when paired with a light shell, it's great in everything but the most frigid weather.

Worn on its own or with a base layer, the women's Quilted Hybrid Jacket from The North Face retains warmth with a thick but stretchy polyester blend that pulls moisture to the exterior. More snug-fitting hoodie than jacket, this top includes thumbholes to help protect your hands from the cold.

Gramicci's men's Cross Country Zipneck is made from soft, stretchy Merino wool, and it benefits greatly from the fiber's ability to create breathable air pockets that hold in body warmth even when wet. This midweight shirt is best worn over a base layer in cool conditions or under a light jacket in colder weather.
