The X-Tex Light Finnfill underwear is made of a technical four-layer material that is breathable, elastic and waterproof. The insulation layer is Finnfill fiber and the intermediate layer is breathable and waterproof X-Tex® membrane. The surface material layer is elastic tricot fabric and the inner layer is pleasant fleece. Finnfill fiber has been developed in cooperation with the world's most prominent research institutes and polymer manufacturers. The structure of Finnfill thermal insulation is unique. Its cohesive element is located in the weft in the middle of the fibers, to which the insulating fibers attach. Because of this, it is an extremely flexible, airy and particularly durable insulation. The difference to traditional non-woven wadding is crucial: Finnfill does not clump, crease or fall apart even after years of use. Finnfill withstands countless water washes without losing its insulating ability. When the Finnfill insulation is laminated to a breathable and waterproof membrane, the fleece lining and the polyester-based outer surface create a whole that moves underwear into a new era. The waterproof and breathable structure of the suit material is patented. The suit has e.g. vents in the armpits and for diving use on the left arm, double-lock front zipper, zippered chest pocket, generous thigh pockets, elastics in the collar, cuffs and ankles, and a sturdy waist elastic. Thumb loops and a leg elastic band make it easier to put on, preventing the sleeves or legs from riding up during dressing.
