Heavyweight merino half zip for proper cold days from the hill to everyday wear.
The Icebreaker Merino 300 Original Long Sleeve Half Zip is a warm, 100% merino midlayer designed for winter missions, travel and daily use when you want reliable natural insulation. The heavyweight 300-weight knit traps heat yet still breathes, helping regulate your temperature whether you are layered up for the mountains or cruising around town. A versatile half zip lets you open things up when you are on the move, while the ribbed collar, cuffs and hem help seal in warmth and keep the fit tidy. With merino’s naturally soft, odour-resistant feel against the skin, it is a go-to pullover you will reach for all season.
