Great thermal leggings

Yes, I recommend this

Great thermals, nice and long too. Perfect for skiing as they didn’t ride up when tucked into my ski socks (an issue I’ve had with other thermals). They kept their shape and weren’t see through either - winners all around

SO Warm

Yes, I recommend this

I had never bought these leggings before so I thought I would give them a try. Bought 2 pairs grey and black. They are brilliant. Well fitting and so so warm. Liked them so much I then purchased a navy pair. It would be nice if there was a wider range of colours for the next Autumn/winter.

Could be better

Leggings too long in the leg have just purchased a navy pair in a smaller size (10) to try and alleviate this problem. After one wear have noticed they are Pilling which is disappointing. Have purchased all thermals produced by M&S for years do find they go quite baggy. I do however appreciate the brushed thermals.

Fantastic leggings, incredibly comfortable and so warm. One of the best pair of leggings I have ever worn. Highly recommend!! Unfortunately couldn’t get black, as all sold out, that popular. Hope they bring the black ones back.
