Vætrex™ Bottoms:

The quilted VÆTREX™ pants were developed together with the quilted top to provide maximum protection. For the best insulation possible, the bottoms can be worn as an undergarment.  The bottoms feature an adjustable waist and articulated knees to enhance performance and fit.  Just like the tops, the pants come in two levels of protection for different temperatures: -30° F and 0° F.
