I bought three of these leggings in different colours and they are great!
So comfortable, just the right amount of warmth and they even look good, much nicer than trackies.
I wanted the size 16, so bought the 16-20 size and they stay up well and are generous in the leg length which is great for me because I never want ankle-freezers.
I love the generous pockets which are very handy.
I recommend these 100%.
