A soft, ultralight merino baselayer, the Men's 150 Merino Long Sleeve Top is made from 100% merino wool for everyday comfort. Providing natural softness, temperature regulation and odour resistance, merino wool is one of natures finest fibres. Working to keep you cool in the heat and warm when its cold, merino wool is highly breathable absorbing moisture vapour before allowing it to evaporate into the air so you stay comfortable for longer. Grown on the backs of merino sheep, merino wool is a naturally renewable and biodegradable fibre.
