Merino wool is a year-round material that regulates temperature fluctuations, remains comfortable even when damp, and requires less frequent washing compared to synthetic fabrics or cotton. The Breeze Plus collection tank top is an excellent choice for various sports activities and leisure in warm weather. *Note!* Unlike in some products, the "plus" in this products name refers to the fabric, not the fit: instead of the regular 150 g/m² fabric used in the Breeze product family, this product is made with 200 g/m² fabric. - Wool has natural stretch, providing a close but comfortable fit - Merino wool fiber thickness: 18.7 microns (extra fine quality) - Machine washable at 40°C; do not use bleach or fabric softeners - Made in Europe Like all the merino wool products we sell, this top is mulesing-free, meaning no painful procedures have been used on the sheep.
