Which size should I choose?

The guide is based on weight: M up to 47 kg, XXL 67–77 kg, XXXL 77–87 kg.

Can it be worn on its own?

It is designed as a base layer, but the matte finish of the knit makes it suitable for wearing at home.

How should it be cared for?

Hand wash in cold water; lay flat to dry (never hang).

No: it’s the silk that’s against the skin, not the cashmere.

Does it really keep you warm?

Yes, without added bulk—that’s the principle of the natural base layer.

Discover the silk cashmere thermal leggings: warmth and comfort every day

A long silk and cashmere underwear, thin and stretchy, that keeps you warm without ever weighing you down. The ideal thermal base layer to get through winter with elegance.

Excellence in Craftsmanship

Silk & cashmere: the warmth of cashmere and the softness of silk, in a fine, second-skin knit.
High stretchability: a stretch fit that hugs the silhouette and follows every movement.
Invisible base layer: thin enough to wear under pants, warm enough to heat cold days.
Thirteen shades: a rich palette, from Matcha Green to Grayish Mauve, to vary the pleasures.

Why Choose Natural Silk?

Natural silk lets the skin breathe, regulates temperature, and limits irritation. Hypoallergenic and delicate, it cares for your skin every day.

Selected by StudioSoie for the nobility of its silk and its refinement — the art of detail, without compromise.

The silk cashmere thermal leggings are designed to offer optimal comfort while ensuring lasting warmth during cold seasons. Thanks to the unique combination of natural silk and soft cashmere, these long women's underwear combine elegance and functionality. Its stretchy material perfectly adapts to all body shapes, ensuring remarkable freedom of movement. Whether for daily use or as a base garment for your winter outfits, these thermal leggings combine exceptional softness and effective thermal insulation.

A noble blend of silk and cashmere for unmatched warmth

These thermal leggings combine the fineness of silk with the luxurious warmth of cashmere, creating a fiber that is both lightweight and extremely warm. Silk provides incomparable softness to the touch while regulating body temperature. Cashmere, well known for its insulating properties, retains heat optimally without causing overheating. Together, these natural materials effectively protect against the cold while remaining breathable, ensuring lasting comfort even during long winter days.

A stretch design for a perfect fit and freedom of movement

Designed to perfectly fit the female silhouette, these thermal leggings benefit from great elasticity thanks to their stretch fabric. This feature guarantees optimal support without compression, promoting mobility during daily or sports activities. Elegant yet functional, they can be easily worn under thicker clothes or alone under a tunic. This flexibility makes the leggings essential for those seeking both performance and style in winter.

Easy care and durability for daily use

In addition to comfort and warmth, these silk cashmere thermal leggings are designed to last. Easy to care for, they retain their insulating properties and elasticity even after several washes. A gentle cleaning is enough to preserve the quality of the noble fibers. Their robustness allows frequent use without deformation. This smart and practical garment quickly becomes a wardrobe essential for women to get through winter with peace of mind.
