What to Wear Running in 15 Degree Weather
A general guide. For your exact conditions, check your city.
Layer up: a thermal base, an insulated mid, and a wind-blocking outer, with thermal tights, a beanie over the ears, gloves, and a buff for your neck and face.
The short version
Fifteen degrees is cold, dry running weather that rewards good layering. A thermal long sleeve, a light insulating layer, tights, a hat, and gloves cover most runners, with a wind shell added when it is breezy. Expect the first mile to feel brutal and the rest to feel fine.

At 15°F you want a three-part top: a snug wicking base, a thermal or fleece mid layer, and a thin wind-blocking outer when the breeze picks up. Thermal tights handle the legs, and thick or merino socks plus a hat that covers your ears finish the kit. Gloves are usually enough here, but runners with cold hands should step up to mittens. A buff around the neck is useful because you can pull it over your mouth into the wind and drop it once you warm up.
The typical mistake is dressing so warmly that you overheat within ten minutes, then stripping layers and tying them around your waist. Layers you can unzip or remove are better than a single bulky piece. The other mistake is neglecting the face and hands, which are the first to complain at this temperature. A smear of balm on cheeks and lips, and mittens you can pull thin gloves out of, transform the run. Avoid cotton, which holds sweat and chills.
Effort makes a big difference. Easy runs and run-walk intervals need the full set, while a tempo or interval workout leaves you comfortable with one less layer once warmed up. Wind chill can make 15°F feel closer to 0°F, so choose a route that starts into the wind rather than ending in it. Keep your first mile easy to protect cold legs from strain, and treat patches of black ice with respect by shortening your stride.
