Warm, second-skin merino-blend base layer for women who want seamless comfort and zoned breathability on cold, high-output missions.

The Icebreaker Womens Merino Blend 260 ZoneKnit Seamless Long Sleeve Crew is a performance-focused thermal top using a midweight merino-blend knit with engineered ventilation zones. The slim, seamless construction hugs the body without restriction, reducing friction under pack straps and harnesses while the ZoneKnit technology maps mesh panels to key heat zones for targeted breathability during hard efforts. The blend of merino wool, TENCEL Lyocell and synthetics balances softness, moisture management, quick drying and stretch, so it feels like a true second skin on ski tours, trail runs or technical hikes. Finished with a classic crew neckline and body-hugging silhouette, it layers cleanly under mid layers and shells with minimal bulk.

Waterproofing	Non-waterproof merino-blend knit designed as a breathable thermal base layer under a shell rather than a weatherproof outer
Warmth	260 midweight warmth system provides substantial insulation and temperature regulation for cold conditions and high-output activities
Fit	Women’s slim, seamless fit designed to sit close to the body for low-bulk layering and a smooth, second-skin feel

Merino-blend fabric: Mix of merino wool, TENCEL Lyocell and synthetics for softness, breathability, stretch and fast drying.
ZoneKnit engineered mapping: Strategically placed mesh, rib and pique structures in key heat zones to boost airflow and manage sweat.
Seamless construction: Minimises chafing and improves comfort under packs and outer layers during dynamic movement.
260 midweight system: Ideal for cold-weather training, ski touring and winter hiking where you need both warmth and breathability.
Slim, second-skin feel: Hugs the body for efficient moisture transfer and easy layering without excess fabric.
