This Norrona men’s Round Neck is a classic merino wool base layer developed for the any-season outdoor lifestyle. An 89% merino wool blend provides natural odour-resistance, moisture-wicking warmth, and a super-soft feel against the skin. The merino wool is from traceable mulesing-free Australian sheep. 11% polyamide is durable and quick drying. At 170 gr/m2, it's the perfect thickness for regulating body temperature in sunny climates or during winter activities.
