I bought Primark's super cosy tights last winter. My friend in work had been raving about them telling me that they are fleece lined and boy am I glad I bought these! I recently took a trip to Montrèal and I took these tights with me. It was so cold I wore my super cosy tights and my jeans.
In the UK they are perfect as the wind chill is none existent, you can wear them with a dress or shorts and they will keep you nice and toastie. They are a little expensive at £3.50, for Primark, as they bobble quite easily.
I have found a Canadian equivalent from Ardene. They are just as warm, but they are a little short in the legs and I am constantly pulling them up. The packet just says the size is small/medium or medium/large. There is no size guides on the back. I bought the small/medium, but this unfortunately is too small for me. I bought 3 pairs of these tights for $15.
Have you purchased them? What did you think?
