Merino Underwear & Baselayers
The merino sheep came to Australia and New Zealand via North Africa and Europe. Today, both countries are among the largest producers of merino wool. Since the end of the 2000s more and more sportswear manufacturers have discovered the advantages of this fantastic material. Merino wool is softer than any other wool and cotton, protects against the cold, doesn't scratch, is odour-resistant and breathable. These attributes make it the ideal material for functional sports underwear. At Addnature, you'll find merino underwear for sports & leisure and for cold & warm weather in the form of long & short shirts, briefs, trousers, shorts and bras.
