This casually cut Merino Ashby Long Sleeve Shirt for women is made from fine merino wool and organic cotton (GOTS certified) in order to provide you with the right climate, maximum comfort, and freedom of movement when in the mountains. Durability has been achieved by means of a new spinning process in which fine polyamide filaments are spun around a merino wool core. This makes the material tear and scuff resistant – without sacrificing the benefits of fine wool fibers.
