Layering for winter running can be a challenge. If you start with an ultra-thin, moisture-wicking top like you wear most of the year and pair it with a light shell, chances are you’re going to stay cold. But if you add a fleece insulation layer, that probably makes you too hot. The solution: Change to a base layer with some insulation like the Waffle Layer by Tracksmith. This 100% Merino wool top is naturally moisture-wicking and odor-resistant. The waffle pattern in the fabric traps air against the skin to increase insulation, but it also helps excess heat to escape once you warm up. The soft and cozy next-to-skin feel is welcome on cold winter mornings — it may just provide the boost of motivation to push you out the door. When the sun’s out and the temperature isn’t too low, you can wear this on its own. Add a jacket for protection from the wind and rain, and you’re set for everything but the most frigid conditions. The piece is so comfortable — not to mention good looking — that it just may become your go-to top for any winter activity.
