Women's Base Layers

Fight the chill with our range of women's thermal base layers. Featuring tops, bottoms, and thermal headgear crafted from premium merino wool, and natural and synthetic fibres, ThruDark's base layers for women offer first-class thermal regulation and breathability.

Fight the chill with our comprehensive women's thermal base layers collection, featuring tops and bottoms crafted from premium merino wool and natural and synthetic fibers. Our range delivers first-class thermal regulation and breathability, engineered specifically for women who demand uncompromising performance in challenging conditions.

Our revolutionary Stealth Seamless base layers utilize the latest in fabric innovation with seamless construction, compression technology, and targeted micro ventilation body-mapped across critical areas to improve moisture wicking during dynamic activities. The advanced Merino X Polyamide blend maximizes insulation and moisture wicking capabilities, with natural qualities capable of performing even when wet.

Merino wool offers unparalleled thermal regulation and odor resistance compared with other natural fibers, delivered at remarkably low carry weight. Its fine structure improves wearability next to skin and can absorb as much as 30% of its weight in moisture without feeling wet, keeping you dry even in demanding conditions. The addition of hydrophobic polyamide lends additional synthetic water resistance and bolsters anti-pilling characteristics for enhanced durability.

Our women's base layers are fully capable of functioning as a first layer in sub-zero environments or as a single layer in milder climates. The seamless construction eliminates chafing and pressure points, while compression technology provides muscle support and enhanced circulation during high-output activities.

The collection includes both base layer tops and bottoms, each featuring the same advanced Stealth Seamless construction and Merino X Polyamide blend. Targeted micro ventilation zones are strategically placed across critical areas for optimal moisture management, while the seamless design ensures comfort during extended wear under additional layers.

Whether you're tackling winter mountaineering, cold-weather hiking, skiing, trail running, or any demanding outdoor pursuit, our women's base layers provide the essential foundation for your layering system. The combination of natural merino wool properties with synthetic performance enhancements creates the perfect balance of warmth, breathability, and moisture management for active women in extreme conditions.
