The Alto Wool Crew shirt combines the properties of merino wool and ultra-soft Tencel-Lyocell fiber. Merino wool provides warmth and regulates temperature fluctuations, making it an excellent material for activities that alternate between movement and rest. Tencel, on the other hand, is an extremely soft and quick-drying fiber made from wood pulp. Thanks to its materials, the Alto Wool Crew is a prime example of following sustainable development principles: the product is made from renewable materials, and if you manage to wear it out, the materials are biodegradable. The Alto Wool Crew is a great choice as a warm mid-layer shirt or loungewear. - Relaxed fit - Fineness of merino wool fiber: 19.3 microns, which is very fine - The wool comes from an Australian farm that does not practice mulesing - Tencel fiber is sourced from Europe - The fabric is made in Sweden - The shirt is made in Latvia - Traceable material in accordance with the "AME Traceable" program - Nature Texx Plasma tre
