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 everyday 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.
