Winter workout wear

Insulating layer: You're getting warmer
Your second layer of clothing provides you with extra protection from cold temperatures. Choose loosely-fitted sweatshirts and long sleeved T-shirts made of lightweight, moisture-wicking and water-resistant fabrics. "We typically recommend a performance fleece that will allow moisture to move outward but retains heat," Stanton says.

An additional layer of running pants may or may not be necessary depending on the thickness and warmth of the tights worn for the base layer. If you decide that you'd like the extra warmth, Stanton recommends wind-proofing materials like, Power Sheild, Windpro, and SuperMicroft.

Winter accessories are also important for keeping warm while working out. Since up to 50 per cent of the body's heat can be lost through your head, Stanton recommends, "moisture-management toques like Dryline if you heavily perspire; if not, insulating fleeces work great."

Waterproof, lined mittens or gloves are also key. "My all time favorite materials for mitts and gloves are Dryline and Windpro -- warm but not bulky," Stanton says.
