Icebreaker Women's Merino 260 ZoneKnit™ Long Sleeve Half Zip Base Layer, Java/Summit

A heavyweight merino wool base layer top designed to help regulate temperature during high-intensity activity, the 260 ZoneKnit™ Long Sleeve Half Zip is the ideal choice for cold-weather training and adventures when you’re moving fast. Made with 100% Merino wool that's breathable and naturally odour-resistant, the ZoneKnit also features strategically placed panels of eyelet merino mesh to help actively regulate body temperature, and a half-zip design for easy on/off and quick heat dumps. Raglan sleeves and gusseted underarms provide enhanced mobility, and flatlock stitching helps reduce friction.

Inspired by nature, icebreaker harnesses the performance qualities of natural fibres to offer an alternative to clothing based on petrochemical synthetics. Merino wool is an annually renewable fibre that naturally resists odours, keeps you cool when it’s hot and warm when it’s not, and lets your skin breathe for comfort all day, every day.
