When winter workouts don't hold you back, reach for The North Face Momentum 1/2 Zip long sleeve top. The Momentum 1/2 Zip features a combination of soft jersey fleece and polyester wrapped around your core for lightweight protection against the cold, while a half-length zipper and bubble-knit stretch fleece panels on the sides increase ventilation when you're working up a sweat. Reflective piping on the backside makes you more visible during morning and evening workouts when the winter sun rises late and sets early, and a stealth security pocket on the sleeve stores small objects like a car key or ID.

• Zipper guard prevents chafing on your chin
