These are lovely soft, cosy and comfortable fleece leggings, perfect for the colder weather inside or out. They are the perfect length too. Very happy, have bought a second pair.

Perfect

Set for winter with my many thermals. Love the softness and cosiness of heat gen. I always go at least a size bigger for all heat gen, they are fairly skintight which I don’t like.

Warm and cosy!

Yes, I recommend this

Very cosy and warm but long! I love them and I wish M&S provided a short length because at 5’2 they need to be turned up when I wear them under the boyfriend jeans.

Perfect for working from home!

Bought to go with the matching top - lovely cosy material which is thick enough to provide enough coverage to wear out of the house. Washes really nicely and hasn't 'bobbled' yet... Strange that they don't do the leggings in the same colours as the tops are available in but the black option works well.

Warm and snuggly

Yes, I recommend this

I love the M & S range of thermals. They are lightweight but warm and don’t cause bulk under other clothes. Having reached an age where I feel the cold I find these garments add a lovely unobtrusive layer to keep me snug. Washing and drying is a dream.
