Our Flex360 Insulation fabric consists of three layers, breathable insulation fibers and polyester soft coating from the top, that is also wind-resistant.

Another materials used in this undersuit are PrimaLoft® Gold Insulation, Embossed Polar fleece (Double pique, 300g/m2, lamination) and 3D mesh spacer pads in the chest area.
