The men’s Wool T-shirt is a merino wool first layer by Norrona designed for outdoor activities in any season. It’s made from temperature regulating and breathable 89% merino wool that’s 17.5 microns thick. 11% polyamide makes this T-shirt more durable, quick drying, and with a softer next-to-skin feel. It’s weight, and the fabric thickness delivers the perfect temperatures regulating blend for cool-weather activities, providing warmth even in wet conditions. Merino wool is also naturally resistant to microbial growth, reducing odour build-up. Norrona sources its wool from mulesing free and traceable Australian bred sheep living on grass and water.
