Our comfort ratings are based on tests simulating a 28-year-old man of average build wearing appropriate layers. We use "warm," "warmer" or "warmest" to help you compare warmth across our footwear and outerwear selection. The temperature shown represents the product's comfort rating during moderate activity, such as jogging a short distance or snowshoeing.
When you select outerwear or footwear, please consider your personal response to cold, your activity level and local weather conditions.
