Icebreaker 320 Original Long Sleeve Half Zip - Mens Jet Heather

The Icebreaker Original Long Sleeve Half zip is one of our earliest designs, and has developed an iconic status as one of the most versatile sweaters a guy can own. This timeless classic is made from 320gm pure merino Jersey, a very soft, breathable, warm fabric that resists pilling, fights odor naturally, and looks great in every environment. The Original Long Sleeve Half Zip makes a great midlayer for skiing, a warm but breathable top for hikes in cool to cold weather, or a refined top for adventures in the city.

Traditional Wool

Thick fibers make it warm, but heavy, itchy and slow to dry.

Synthetic

Plastic fibers make it lightweight and fast drying, but clammy, stinky and highly flammable.

ICEBREAKER MERINO

Thin, natural fibers make it warm in cold weather, cool in warm weather, light, breathable, easy care, no stink and no itch. And did we mention renewable and biodegradable? That's because it's made from grass, water and sunshine, rather than petrochemicals.

One of our earliest and best-loved layers, the classic Original Zip is made from expedition-weight 320gm pure merino fabric and is designed to move easily between the outdoors and the city. Click Here For Size Chart
