The essential piece you throw on without thinking and won't take off all winter. The Mania undershirt is a very fine merino wool knit, a perfectly designed turtleneck, and a second-skin effect that slips under anything: a shirt, a blouse, a jacket, a dress.

• Material: 100% merino wool
• Fit: close-fitting, second-skin effect
• Collar: turtleneck
• Sleeves: long
• Length: hips
• Very fine knit

Merino wool is a naturally fine, soft, and thermoregulating fiber: it warms without ever stifling and remains comfortable worn directly against the skin. This undershirt makes the most of it, with a flexible knit that hugs the silhouette without compressing and a clean drape that doesn't lose its shape. The equally flexible turtleneck protects the neck without being restrictive, while the fineness of the knit prevents any bulkiness under a shirt or jacket.

This is the ultimate layering piece. Wear it alone with wide-leg jeans and ankle boots for a streamlined look, under a lace blouse or a slip dress to extend the warm season, or under a blazer and tailored trousers for a sharp office look. Navy blue, softer than black, matches all the colors in your wardrobe.

• Invisible warmth: the fineness of merino wool warms without adding any bulk.
• Unlimited layering: it slips under a shirt, jacket, sweater, or dress without ever adding bulk to the silhouette.
• Second-skin comfort: its flexible knit follows your movements and remains soft all day long.

This merino wool undershirt is particularly recommended for women looking for a warm, thin, and timeless base layer, to be worn alone or as a first layer throughout the cold season.

How does this undershirt fit?
Its cut is deliberately close to the body, with a second-skin effect: we recommend taking one size up from your usual size.

Does merino wool itch?
No. The fineness of its fiber makes it particularly soft, allowing this undershirt to be worn directly on the skin.

How to care for it?
Wash it by hand, without bleach, wring and dry flat, then iron it inside out at a low temperature. Professional dry cleaning is also possible.

Adopt this merino wool undershirt, the most useful base for your winter.
