Warm soft comfortable

Silk pants

My aunt liked the terramar pants I sent her as a present. I would have liked to have been able to provide a gift receipt or some way to hide the price when I sent her the pants though.


These silk long underwear are luxurious to the touch and keep me warm!

Thermal silk pants

Warm and wonderful

I've had my first pair for over thirty years, and am wearing them today.

Today when I put on my trusty silk layer from TerraMar, I noticed that the on the top of the the lower thigh
the fabric is beginning to have small holes from wearing through. But I first bought these more than 30 years ago! I ordered them
before I went on a winter trip to Chiapas, Mexico, in the mid 1980's.
I have worn them regularly every winter since then, since I live at high altitude where we have harsh winters.
Though I have other base layer pants, these are by far the most comfortable. They are lightweight and after all these years
they have not lost their shape.
I am going to buy another pair since these are beginning to slightly shred on the thighs. I can only hope that
the new product is as good as the ones I bought originally and will see me as well. Amazing product!
