An ultralight merino base layer top designed to help manage sweat during high-intensity activity, the 125 ZoneKnit Long Sleeve Crewe is the ideal choice for cool-weather training and adventures when you’re moving fast. Made with icebreaker's jersey Cool-Lite fabric that blends natural merino wool with TENCEL Lyocell to manage sweat and resist odours, the ZoneKnit also features strategically placed panels of eyelet Cool-Lite mesh to help actively regulate body temperature. Raglan sleeves and gusseted underarms provide enhanced mobility, and flatlock stitching eliminates chafing. Soft merino and TENCEL Lyocell, sourced from sustainable eucalyptus plantations, combine to create icebreaker Cool-Lite, a fabric that helps to regulate your body’s microclimate. Inspired by nature, icebreaker harnesses the performance qualities of natural fibres to offer an alternative to clothing based on petrochemical synthetics. Cool-liteCool-lite combines merino with TENCEL a natural fiber sourced from sustainable eucalyptus, that helps heat dumping and wicking to enhance cooling in the heat of the day. The merino component resists odor, breathes and regulates temperature when it turns cooler.
