For ultimate protection in extreme cold. Featuring a dual layer of performance insulation for maximum warmth and comfort. The X35S are our warmest freezer salopettes to date! They have two layers of high performance insulation to keep the warmth close to your body. The combined weight of both layers is 350gsm up to the waist. 200g insulation is used on the body so that these salopettes can be worn comfortably alongside the X35J Jacket. Typically used by drivers who work in the deep freeze. These salopettes are perfectly suited to lower activity job roles due to the dual layers of insulation.
