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.

Too long

Yes, I recommend this

Unfortunately these leggings were too long as I’m a petite 5’1” and they cannot be shortened successfully due to the stretchy fabric. I wish they were available in a Short fitting as they seem lovely and warm and would have been ideal for when I’m working outside in the freezing cold.

Larger than its stated size

No, I don't recommend this

Material is soft and very comfortable. I gave 3 stars because I purchased a size 10 but it was too big for me, it fits more like a size 12. Since I only use it as a thermal layer for skiing I decided to keep it, and I tuck one of my thermal tops inside the waistband to hold the leggings up.

Warm but thin

Not as thick as the ones I purchased last year so not quite as warm. Probably better for spring than winter.

Nice leggings. Questionable political leanings

No, I don't recommend this

Leggings fine, but I won’t be buying anything from Marks and Spencer again unless you stop funding hate when you advertise on GB news. You have lost another customer.
