Optimal comfort and breathability in cold conditions
The Icebreaker Merino 250 Vertex Mens Thermal Long Sleeve Shirt is a midweight merino base layer top for optimal comfort and breathability in cold conditions. The super soft and breathable 250gm jacquard fabric is made from 100% merino wool, and the half-zip design allows for easy layering and quick temperature regulation. Underarm gussets increase range of motion. And what’s more it has a snug, close-to-body fit for low bulk layering.
Inspired by nature, Icebreaker harnesses the performance qualities of natural fibres to offer an alternative to clothing based on petrochemical synthetics. Merino is an annually renewable fiber that naturally resists odours, keeps you cool when it’s hot and warm when it’s not, and lets your skin breathe for comfort all day, every day.
