EMS Northshield Pants
Here's what other sites are saying:
Technical hybrid construction, an articulated fit, and stretch mobility make these pants ideal for Nordic skiing, cool and cold weather running, and other highly aerobic winter activities. The front of the pants have been engineered to provide a windproof, water-resistant barrier where you need it, while fleece-lined jersey in the seat and back of the thighs delivers breathable, moisture-wicking comfort. Runners and cross country skiers will find that these pants are warm enough to be worn on their own without a layer underneath in most winter conditions.
