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.

Unable to test product due to early spring, friend who recommended states they are indispensable to an Iditarod race. Construction appears to be very Good, unable to rate further due to the early spring.

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.
