Stretchy, comfortable and warm, this tight is perfect for cross country skiing at moderate intensity in cold weather.  Windproof on the front and breathable on the back, it's got a drawcord waist, reflective features for safety and a lower leg zip. The fit is trim and with the brushed fleecy lining these can be worn comfortably with no base layer if it is not too cold, and are surprisingly warm when layered.
