One of Icebreaker's earliest and best-loved layers, the Men's Original Zip-Neck Sweater uses expedition-weight merino wool so you can move easily between the outdoors and the city. The merino wool keeps you warm when you're wandering around downtown and helps you cool off when you step inside a heated coffee shop. The forward side seams don't rub, and the rib collar keeps chill wind at bay.
