Constructed using hollow fibre technology, Insulatex™ provides a lighter and warmer thermal lining. The unique fabric technology locks in the body's warmth to create a thermal barrier whilst the high-performance fine knit offers superior lightweight comfort to the wearer without adding bulk.
InsulatexPro is Portwest's most advanced lightweight thermal lining with supreme warmth-to-weight ratio.
Three times warmer than standard insulation, the soft insulating fabric has millions of air pockets that trap air and body heat offering maximum protection in extreme cold and wet conditions without weighing the wearer down with excess weight.
