Pro tip: For best results, wash your silk thermals inside a mesh laundry bag to protect the delicate fibers and extend their lifespan

These silk thermal sets run true to size with a comfortable, form-fitting design that layers perfectly under clothing. The stretchy silk fabric naturally conforms to your body shape while maintaining its elegant drape. For a looser fit or if you are between sizes, we recommend sizing up one size.

Note: Please refer to our size chart and measure yourself before ordering to ensure the perfect fit for maximum comfort and warmth

What makes mulberry silk thermals better than regular thermal underwear?
Mulberry silk is nature's finest insulator, providing exceptional warmth without bulk while being incredibly soft and breathable. Unlike synthetic thermals, silk naturally regulates temperature, wicks moisture, and is hypoallergenic — making it perfect for sensitive skin and all-day comfort.

Can I wear these silk thermals under my regular clothes?
Absolutely! These thermals are designed with a slim, form-fitting cut that layers seamlessly under any outfit without adding bulk. The smooth silk fabric won't bunch up or create visible lines, making them perfect for wearing under work clothes, casual wear, or activewear.

How warm are these silk long johns compared to wool or fleece?
Silk provides comparable warmth to merino wool but with superior breathability and moisture-wicking properties. The natural protein fibers trap warm air close to your body while allowing excess heat and moisture to escape, keeping you comfortable in temperatures ranging from cool autumn days to freezing winter conditions.

Are these thermal sets machine washable?
While hand washing is recommended to maintain the silk's luxurious quality and extend its lifespan, you can machine wash on a delicate cycle using cold water and a mesh laundry bag. Always use a gentle, silk-friendly detergent and avoid bleach, fabric softeners, and high heat drying.
