Don't let the cold affect you. The unique combination of Polartec ™ and ripstop nylon creates an insulation system designed to keep you warm and dry during cold weather runs.

Polartec ™ reigns supreme in winter and cold weather running. It sets itself apart from other types of insulation by trapping air heated by your body, while being lightweight enough to retain quick-drying properties suitable for high-intensity rides in winter conditions. It is designed specifically to keep you warm and dry, not warm and damp.

This top combines Polartec ™ with strategically placed nylon ripstop arm patches that enhance quick-drying properties, decrease weight and increase ventilation. And unlike conventional insulation, this top traps dry heat, eliminating that clammy cold, even when you're not moving.
