What is Vætrex™?

Vætrex™ is our trademark and stands for Vapor Attenuating and Expelling, Thermal Retaining insulation for EXtreme cold weather.

Northern Outfitters Vætrex™ technology, the foundation of our clothing and gear, is known all over the world as the most efficient cold weather product on the market today.  A study done by Professor Wayne Seames, PhD., of the University of North Dakota Department of Engineering found:

"Vætrex™ is the clear winner for cold weather performance. Ounce for Ounce, Vætrex™ is simply the most efficient insulating material currently available for cold weather clothing applications."

How it works 

Our Vætrex™ technology is designed to be worn directly against the skin. Vaetrex has superior wicking and heat retention properties which can be degraded by wearing natural fibers between the sikin and our technology.

All of our Vætrex™ technology is Made in America by

The National Industries For The Blind
