The ZoneKnit Insulated Long Sleeve Hoodie Men by Icebreaker is a mid-layer designed to keep you warm and comfortable during cooler days in the outdoors. It combines merino wool’s natural warmth and breathability with a slim, streamlined fit, making it a versatile piece for hiking, camping or everyday wear when temperatures drop.
Built using Icebreaker’s ZoneKnit™ body-mapping technology, this hoodie delivers extra insulation where you need it most and enhanced ventilation where you sweat. The outer and inner layers are 100% merino wool, prized for its ability to regulate temperature and manage moisture without smelling over time. Between these layers, an 88% wool and 12% polylactic acid fill adds loft for warmth while keeping the garment lightweight and resilient.
ZoneKnit™ works by varying the knitting patterns across different zones of the garment: tighter knits trap heat in cold-sensitive areas, while open knits promote airflow in high-sweat regions. The polylactic acid component of the filling is a plant-based fiber that reinforces the wool, helping the insulation maintain its shape and performance wash after wash.

The ZoneKnit™ Insulated Long Sleeve Hoodie is a high-performance merino wool midlayer optimized for intense activity and technical mountain pursuits. This warm yet highly breathable hoodie features icebreaker’s ZoneKnit engineered body mapping, which combines merino jersey fabric with strategic panels of merino eyelet mesh to enhance airflow and temperature regulation. On the chest, a panel of MerinoLoft™ insulation, a natural and cruelty-free merino fill, adds key core warmth where it’s needed most. The balaclava hood increases protection, while underarm gussets and raglan sleeves provide uninhibited range of motion.
Inspired by nature, icebreaker harnesses the performance qualities of natural fibres to offer an alternative to clothing based on petrochemical synthetics. Merino 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.
