NEXTTwo Italian researchers working in the 1960s discovered a way to spin polypropylene into yarn. Helly Hansen took advantage of the new technology and commercialized a hydrophobic baselayer that pulls moisture from the skin using O-shaped stitching on the inside and X-shaped stitching on the outside. The O-shaped stitching allows water to evaporate from the inside of the garment to its surface, where X-shaped stitching prevents it from reabsorbing.
