silk underwear

I purchased Thermasilk underwear 25 years ago and it's still going. Was happy to see it still available and recently purchased a long sleeve white undershirt. It's wonderful! Exactly as before. Warm, light and great for everyday and especially travel. Thank you!!!!

Replacement of same

Replacement of top of long underwear.
2022 style is a little more scoopy which is what I had in mind for the past 10 years.

Still the same!

I bought my first Terramar silks in the 1990’s. One was black, and I wore it and washed it so often over ten years, that it fell apart. The other was magenta and I treated it more carefully, and I wear it still. Last week, on a whim, I googled ‘Terramar’ and was happy to see that the exact same black silk was still available. I hope to wear my new black silk for many years to come. Thank you for staying the course. So many things change, it’s a delight to have something stay the same!

Lightweight yet warm

I ordered to replace my “silks” purchased at least 10 years ago. Am hoping the quality is still as good as years ago. The undersilks are very lightweight and provide warmth under sweaters and jeans without being heavy or bulky. I will continue to purchase this brand as long as they continue to make excellent products.

Love love this top!

I have been wearing these tops for maybe 20 years - and I love them! They are so sheer as to be almost undetectable under my clothes, including dress clothes. I wear them all winter, every day, inside and out and they really keep me warm. Please don't stop offering them!
