Men's Merino 175 Everyday Long Sleeve Half Zip Thermal Top

The Icebreaker Men's Merino 175 Everyday Long Sleeve Half Zip Thermal Top is a classic base layer built for daily use, whether it’s going under a shell on a cold morning or worn on its own when conditions are milder. The 100% merino wool rib-knit fabric is soft, breathable, and naturally odour resistant, with enough stretch to stay comfortable through a full day of wear.

This is the kind of piece that earns regular rotation because it handles a wide range of temperatures well, keeping you warm when it’s cold and cool when it’s warm. Icebreaker uses 100% pure merino fibres that were hand-picked for strength and softness, and the result is a fabric that feels refined without losing the practical, everyday performance merino is known for. It’s also free of plastic microfibres and petrochemical-based synthetics, and merino wool fibre is naturally renewable, recyclable and biodegradable under certain conditions.
