Icebreaker Mens Merino Icebreaker Anniversary Original Long Sleeve Half Zip

We’re celebrating our 30th anniversary by reimagining our classic O-Zip (short for Original Half-Zip) midlayer, using fully fashioned transfer knit construction. The O-Zip is a brand icon, that has been in the line since the beginning, pure merino fibre perfomarmance combined with a contemporary cut inspired by 30 years of design and innovation.
