Added warmth and protection designed for hard-working legs, the ultra light 125GSM Nuyarn merino technology in these leggings offers 5x faster drying and incredible stretch and recovery. Machine washable and remarkably durable, the super-fine 18 micron non-mulesed merino wool is soft and wearable with no-chafe flatlock seams. Moisture management and breathability is simple, thanks to targeted eyelet placement and a gusseted crotch.
