Icebreaker Men's ZoneKnit 260 Half Zip {IC-0A56HF}

Icebreaker’s Men’s ZoneKnit 260 Half Zip is a performance merino wool base layer for high-energy winter sport, including running and cycling. It uses a 260gsm merino construction for warmth, with targeted ventilation zones to help manage moisture during active use. The half zip sits deep for adjustable airflow, while the dropped front and back hem adds coverage.

Zoned 200gsm panels use a vented eyelet merino structure in areas where heat and moisture build, including under the arms and across parts of the back. Flatlock seams run throughout for a smooth feel, and raglan sleeves support unrestricted movement. Thumb hole cuffs add hand coverage when conditions change.
