Product Description

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.

VÆTREX™ Liners are designed to be worn directly against the skin, but can be worn over a thin layer of polypropylene/polyester, or wool/polyester, blend underwear.  Don't wear 100% natural fiber underwear with these liners--it will absorb and retain mositure, which degrades the performance of the VÆTREX™.  We carry two types of long underwear that have been tested with our gear and we know work well with our VÆTREX™ technology.  You can check them out, believe it or not, by clicking on the category "LONG UNDERWEAR" on the left side of your screen.

Use VÆTREX™ Liners with our Arctic Parka Shell, EXP Waterproof Arctic Parka Shell and EXP Waterproof Bib Shell.

    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!

  3. well made and warm 5 Star Review

    Posted by on 1st Feb 2013

    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.
