I'm off to Beijing in Mid-January and I need to get some thermals if I plan to survive the cold. When I went to Marks & Spencer here in Manila (one of the few places that carries thermals in this tropical country) I saw these silk blended thermals which were thinner and lighter than the older ones that I used to have which were wool or cotton blends.

Although they are thinner and lighter, they cost more. 1 pc is the same price for a 2-pack on the cotton blends. I'm really tempted to buy it because it will save a lot of space and weight on my bag...since I need to bring puffy jackets and wool coats too.

I want to know if its just as good or better than the other stuff.
