Thermal Zone combines three weights of Polartec® fabric into one
garment. The heaviest-weight fabric is used in core and maximumexposed
areas for optimal heat retention. Midweight fabric is
employed in less-critical areas that still receive exposure.
The lightest-weight fabric is located in high-heat-output areas that
are prone to excessive perspiration. Choose between the multiseason versatility of
Thermal Zone E.C.W.C.S. with Power Dry or Thermal Zone Stand Hunter with Thermal
Pro, our warmest base layer ever.
