This women’s thermal underwear set is designed as a high-performance base layer, combining advanced high-stretch acrylic fiber with Merino wool for reliable warmth, breathability, and comfort. Featuring a wide scoop neckline, the silhouette stays invisible under outerwear while maintaining a flattering, close-to-body fit.

The fabric blend consists of 48.0% viscose, 39.3% acrylic, 8.6% spandex, and 4.1% Merino wool. This carefully balanced composition offers excellent elasticity, shape retention, and a smooth, soft touch. The added Merino wool enhances natural moisture management, allowing the fabric to absorb up to 30% of its own weight in moisture without feeling damp, making it ideal for autumn and winter wear.

Double-sided brushed wool fabric improves the traditional feel of wool by reducing irritation and enhancing softness. The brushed surface forms a natural protective layer on the skin, helping reduce moisture loss, support skin hydration, and promote comfortable daily wear, especially for dry or sensitive skin during colder months.

With built-in far-infrared warming properties, this thermal underwear set helps retain body heat efficiently, delivering consistent warmth without bulk. The result is a lightweight yet insulating women’s base layer that balances style and function, keeping you warm while maintaining a clean, streamlined look.

The set is constructed using three-dimensional tailoring and seamless hidden stitching techniques. Its one-piece 3D shaping ensures smooth lines, eliminates unnecessary seams, and provides a refined, ergonomic fit suitable for layering under coats, sweaters, or wearing comfortably indoors.

This collection includes three essential base silhouettes, making it a versatile choice for everyday wear, work, travel, lounging, and cold-weather layering.
