Our quilted -30° VÆTREX™ Parka Liner, constructed with our patented insulating technology, is designed to wear with our Arctic Parka Shell. Combined they will keep you warm in temperatures ranging from 20º to -30°F. In an extensive double-blind test performed by the UNIVERSITY OF NORTH DAKOTA, Northern Outfitters VÆTREX™ liners were proven superior to any other garments available for extreme cold weather temperatures. The results of the test concluded: "OUNCE FOR OUNCE, VÆTREX™ IS THE MOST EFFICIENT INSULATING MATERIAL AVAILABLE TODAY." VÆTREX™ is the ideal product for any winter activity.

This design is clearly the best I have ever experienced. As trail wear following the Iditarod Race I was grateful on many occasions for the fine craftsmanship and experience based design. Warm - dry and happy. It doesn't get much better than that!

This is exactly what I wanted! I followed the sizing chart when ordering and am quite happy. A medium fits good even with my long arms and my 6' 1" height. Very effective insulation, this -30 rated stuff can handle all the cold weather Idaho has to offer. I wear thin polyester long johns underneath this vaetrex and then I wear my regular jeans and shirt over them. My jeans and shirt have to be a size larger than what I would normally wear. When everyone else is shivering and headed for shelter I am warm, dry, and comfortable. I could stay outside all day and all night if I wanted in the middle of winter. I am not tough, this is just truly warm, effective clothing.
