What Our Gearhead(R) Experts Are Saying: "I like these for cold morning runs when normal tights just aren't enough. The wind-resistant fabric really cuts the chill, and the insulated panels keep my knees and seat warm without making the whole tight bulky. They also breathe well during high-output efforts, which makes them great for winter training."When the temperature drops but the miles still call, we reach for the Kor Alloy Tight from Mountain Hardwear and head out into the cold.
