Nice thermal leggings

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

These were nice and soft but too thin for wearing on their own which is what I was looking for. If looking for ones to wear underneath trousers these would be ideal. Returned them

Comfy and warm

Originally posted on marksandspencer.com (UK)

Comfy. Accurate size. Legs a bit long for a person of 5’1” but that’s not unusual. Only lost a star because whenever I wear them I am full of static! Mini electric shocks all the time. They do help keep chills at bay though. (And non sweaty like some cheaper brands)

So comfy

Originally posted on marksandspencer.com (UK)

I bought these heatgen leggings in autumn 2023 and used them for exercise classes. They were so comfortable because of the stretch that accommodated my rounded stomach. I was tempted to wear them all the time with a tunic or cosy, long jumper, not just for exercises. Now, in 2024, I have bought a second pair so that there’s always a clean pair available. I will probably buy another pair soon in case M&S decide to discontinue the line. I love them. The quality is excellent, they wash well and I recommend them.

Keep you warm, good quality and value

Great for keeping warm, I wear these as I would regular leggings with jumper dresses and boots or for lounge wear to keep warm instead of turning the heating up.

Poor quality

Originally posted on marksandspencer.com (UK)

Bought a new pair as first pair had split at the seams but I thought I’d over washed but then new pair started bobbling and chaffing on first wear so obviously a poor quality fabric

Love these leggings. I have several pairs in different colours. I wear them under my joggers and trousers for extra warmth when temperatures start to cool down. The quality is very good and they wash well.

Bitty after worn once

No, I don't recommend this

I’m disappointed in the material, as only worn them once under some trousers and they have gone bitty. They are lovely and warm but didn’t expect them to go bitty
