PRICES MAY VARY. Raw Material Advantage: Unlike most 18.5μm Merino wool products on the market, all Merino wool products at Chanyarn are made from 17.5μm Superfine Australia Merino wool, which is of A+ grade quality. This choice incurs higher raw material costs. However, we chose it because it maximally restores the essence of Merino wool—being softer, warmer, more breathable, more skin-friendly, and more suitable for individuals allergic to wool.
