Silk Clothing and Undergarment Warmth Guide
The WinterSilks snowflakes indicate the level of warmth you can expect to receive from that clothing or undergarment. The more snowflakes you see, the warmer you'll be.

The silk guide indicates the level of warmth for clothing and undergarments.
WinterSilks is proud to offer the largest variety of silk long underwear on Earth. From silk's natural ability to insulate while wicking away moisture to its luxuriously comfortable feel, you won't find a better fabric for undergarments. And, not only are most of our silk long johns machine washable, they come in tall, petite, and plus sizes, as well as various weights and blends so you can mix and match to find the perfect long underwear for your needs. Consult our extended Warmth Guide below to customize your layer of warmth for winter and year-round.
Lightweight silk clothing and undergarments are marked with one snowflake.One Snowflake:  Great for high exertion activities, and for everyday use in warm to cool weather.

You'll find the largest variety of styles, sizes, and colors here, from silk accessories to intimates. We also carry lightweight filament silk kids' long johns. Our lightweight long underwear are ideal for chilly air-conditioned offices or supermarkets, as well as cool-weather outdoor activities. Also, filament and interlock silk camisoles, tank tops, and t-shirts provide subtle warmth against spring summer breezes, and they fold small enough to fit in any packed purse or briefcase.
Mid-weight silk clothing and undergarments are marked with two snowflakes.Two Snowflakes:  Wear during moderate exertion activities, and in cool to cold weather.

A lesson in versatility, our mid-weight filament silks allow you to turn the thermostat down in the fall and winter to save on energy costs, and stay toasty warm while snow skiing or enjoying other outdoor winter activities. You'll also find easy-care silk cotton long johns in this category. Mid-weight filament silk long underwear are slightly heavier than our lightweight, but still are thin enough to disappear under clothing.
Heavyweight silk clothing and undergarments are marked with three snowflakes.Three Snowflakes:  The warmest long johns for low exertion activities in cold to frigid temperatures.

For the nastiest of cold weather, our heavyweight spunsilk, silk Thermoknits, and luxurious silk cashmere long johns protect you from the wrath of Old Man Winter. These are the warmest silk long underwear available, perfect as either layering pieces during cold-weather strolls or on their own, as the most comfortable pajamas, for settling down to a warm, cozy nap. Also look for performance-minded Techno Silks in this category.
