Vari-Tech Temperature and Motion Design is a concept pioneered to provide maximum freedom of movement and exertion without sacrificing protection from low temperatures and extreme weather.
Vari-Tech design concentrates insulation in the core body area of the torso where you need it most, and uses light weight laminated insulating layers in the extremeties to prevent overheating which causes excessive sweating.
Additionally, Vari-Tech design allows for full freedom of movement using pleated and articulated construction in the joint areas such as the knees and elbows. Likewise, this desing prevents the fabric from bunching or binding whether you're walking, sitting in a blind/stand, climbing over dead fall, or trudging through the mud.
The Tech-Term "Vari-Tech" is referred to in the following products:
