Base layers provide vital warmth but also look uber cool. Look and feel your best while beating the cooler weather conditions. adidas COLD.DRY Base Layer Print is the layer closest to the skin and should be at hand in the wardrobe when the temperature is down. To ensure maximum effectiveness, base layers should be fitted and not loose. Ant gaps between the skin and fabric can allow the cold to sneak in and spoil the effect. Always go for your actual size in base layers.
