You get what you see!

No, I don't recommend this

As far as leggings go, you get exactly what you ask for. The only thing I wasn't thrilled with was the fact that they were of such thin material and given the word 'thermal' was in part of the heading, I found this to be misleading. However, if the 'Heatgen' technology means that the material would be so particularly light, then so be it. They are very light and would be great as a further insulating factor under trousers in the winter.

Bought to wear under jeans … nice and lightweight so perfect for what I want them for. Sometimes wear them in the evening before bed on top of my sleep shorts, as I can Find the modal sleep leggings you used to sell. (Which I prefer but alas you don’t sell anymore)

Rather disappointing

No, I don't recommend this

Compared to all the other leggings I have purchased from yourselves these were very thin and see through.

Usefull lightweight thermals.

Yes, I recommend this

Good lightweight thermals. Bought to wear under skinny jeans etc, where thicker thermals too bulky. Nice silky feel, true to size but a little long in the legs, but not really a problem.

Great under ski trousers

I found the material of leggings very thin. Around the house they are cold but under my ski trousers they kept me warm.

No colour choice

Yes, I recommend this

I love my M&S longjohns and depend on them throughout the year lately. My lovely pale grey standbys have finally developed holes and must be replaced. New ones are super thin, good quality and very comfortable. However I had vowed not to buy any more black underwear as It's difficult to distinguish easily in my drawer and cupboard shelf. There was no choice with these and just as I feared they disappeared into the void. Can I be the only customer wh would welcome a different neutral colour even if blue was out of the question ?

Deceptively warm

Yes, I recommend this

Lovely and thin but deceptively warm. Go out with my dogs everyday at 7 and wear these under my jeans. They keep me lovely and warm. Wash well, keep their shape and dry quickly. I would definitely recommend them

THESE ARE NOT LEGGINGS

No, I don't recommend this

These are more like footless tights, good to wear with socks long boots and skirt but if you wear as leggings you will look like you have tights on, you can see your knickers through the material

Great for under trousers

Yes, I recommend this

Just what I wanted. Other reviewers mentioned they were thin but that is what I wanted. I don’t want think or bulky leggings as a thermal layer. These are perfect. Wish they came in longer length for taller people though
