We developed our ultra-versatile, midweight 100% New Zealand Merino wool baselayer Zepher fabric using an interlock stitch. This simple, double knit stitch forms a fabric that offers high performance, great natural stretch and recovery. Its smooth surface enhances softness and layering ease. The fabric is "no stink," sustainable and machine washable and is the ultimate baselayer choice.
