Useful lightweight leggings

Very happy with these leggings. Useful for me to wear with a dress or underneath trousers on a cold day. I can find many uses for them and they are so comfortable.

2pk thermal leggings

Yes, I recommend this

These leggings are perfect for wearing under jeans/ trousers. They're thin enough to fit underneath clothes but add a lovely layer of warmth

Good quality

Yes, I recommend this

Have bought these leggings for some years now but why doesn't M&S produce some matching thermal leggings and tops (in these lightweight ones) in some nice colours like they do in the thicker thermal ones. I recently ordered some pale blue lightweight tops and would have loved matching blue leggings.

Warm, lightweight and comfortable

Keeps my legs warm under trousers, very flexible and stay in place. Good fit. Please use Royal Mail as the courier as they are more reliable than Evri.
