Soft and elastic with the chest and sleeves clinging strongly. These are size 12 and I'm usually a size 12 with M&S clothes.

Looks nice

Originally posted on marksandspencer.com (UK)

Nice fit and feels nice to wear, not very warm to wear, more for spring wear, would probably get a higher thermal rating next time, but pleased with fit and wearing it under my fleece waistcoat.

Could be better with some improvements to the fit.

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

They are ok. The fit could be improved by making them two inches shorter, and adding a bit of extra width in the tummy/hip area without making the shoulders and bust wider.

Thermal long sleeve tops.

I put on my thermal long sleeved top this morning for the first time and couldn’t believe how soft and silky it was. It had kept me warm all day with the cold wrather still lingering.

Heatgen thermal vests

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

These vests provide a comfortable and thin extra layer on slightly chilly days. They wash and dry really well too. My only caution is that the sleeves are very long and have to be folded back

Warmth without bulk

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

These are great for providing warmth but not bulk. I hate to feel all bundled up but I also hate being cold! These are the solution to keepiing warm without all the layers.

Love these vests

Originally posted on marksandspencer.com (UK)

I had these vests in black and they are so good I bought the cream version. I’m very happy with them. I like the long sleeves. The fabric is light but warm. It is definitely an undergarment not at shirt but that’s what I wanted. They are close fitting so don’t spoil the line of outer clothes.

These are lovely thermal vests, next time I'll go a size up though as very clingy. Really like the length too. Highly recommend but go up a size.

Great for every day wear

Yes, I recommend this

I wear these all the time under shirts , t shirts etc in winter as a bad layer. Not too hot and perfect for not too cold but damp Irish winters. Have been getting them for last ten years. Consistent sizing and quality

These are fantastic. A soft, thin layer in lovely colours that works really well under anything. Great for. They do roll up a bit from the bottom on me so I tend to tuck them in. Excellent value. I'd highly recommend.

disappointed with the change of fabric.Now contains spantex... which makes it very clingy. Would now need to size up! Ordered 2pack navy.One black and one navy arrived in battered package.

Lightweight with a close fit. A fine knit fabric which kept me warm and a city break to a cold Vienna. They have washed well.

So handy, so warm.

Originally posted on marksandspencer.com (UK)

I already have these tops in grey and blue but kept thinking i could do with a black one. I've worn them so much since buying them - the double pack is actually s blessing in disguise because you can eat one when the other is in the wash! They fit closely to the skin and under a jumper give so much warmth in winter
