All-round merino base layer leggings for anyone who wants reliable warmth, breathability and next-to-skin comfort for cold-weather missions.
The Icebreaker Merino 200 Oasis Thermal Leggings are classic midweight base layer bottoms made from soft, breathable 200-weight merino jersey. Using 100% merino wool (excluding the waistband), they naturally manage temperature, wick moisture and resist odour, making them ideal as the foundation of your layering system for skiing, hiking or everyday cold-weather wear. A slim fit with gusseted construction delivers unrestricted movement, while flatlock seams help prevent chafing when you are active. The brushed elastic waistband sits comfortably against the skin and stays put under pants, bibs or shell bottoms.
| Waterproofing | Non-waterproof merino jersey designed as a thermal base layer under snow or rain shells rather than a weatherproof outer layer |
| Warmth | 200-weight merino fabric provides lightweight to midweight insulation and thermoregulation for cool to cold conditions and active use |
| Fit | Slim, next-to-skin fit with gusseted construction for natural movement and reduced bulk under outerwear |
