Men's Merino 175 Everyday Thermal Leggings

The Men's Merino 175 Everyday Thermal Leggings are the kind of base layer you reach for when you want one bottom that works through most of the year. Built with 100% merino wool in a slim fit, they deliver breathable warmth, reliable next-to-skin comfort and the kind of natural odour resistance that matters whether you're wearing them all day under workwear, travel layers or winter kit.

Icebreaker uses 100% pure merino fibres that are hand-picked for strength and softness, giving these leggings a soft, lightweight feel with rib fabric for stretch and comfort. They’re also free of plastic microfibres and petrochemical-based synthetics. As with merino in general, the fibre is naturally renewable, recyclable and biodegradable under certain conditions. For everyday use, that balance of comfort, temperature regulation and low-fuss wear is hard to argue with.
