First, The product received is not the one in the picture, very misleading. Secondly, These are very thin, I'm a builder and working outside in the winter is slightly cold as you can imagine. I wore these today, did little to help. I would rather pay a bit extra for Marks & Spencer ones. They at lest keep me warm. If you are planning on using these whilst skiing, while I have not tried skiing in these, they do little to keep you warm in 7C Degree weather so I cant imagine them being very useful whilst skiing.
