Great fit.

Yes, I recommend this

Fabulous little top. The neckline is just perfect. Just right to layer things over the top. It's like wearing a second skin. So warm too, seems to trap the heat inside. The fit is just so good, it moves with you can hardly notice (apart from the warmth) that you have it on. I will need more.

Very thin

No, I don't recommend this

A LOT thinner than expected for the cost, not the best heat retention in my view, long sleeve t-shirt would do just as well. Disappointed.

Love these thermals and wear them throughout the winter. Soft & cosy and a good length to keep your kidneys warm.

Lovely thermal top. I have had several of these for some years now so good to see new colours. They are much thinner though but still a warm layer

Love these tops

I wear a base layer throughout the Autumn/Winter as I can't bear to be cold and these are perfect.

A staple for the UK

Yes, I recommend this

I live in these Heatgen tops - they’re thin enough to go under pretty much everything, and they’re lovely and warm. I have some of the thicker ones too (the ones that feel fleecy on the inside), but I still prefer these. They’re like a second skin. My only suggestion for improvement would be to do them in a white instead of (or in addition to) the cream. The cream doesn’t look right under v neck jumpers, so I end up wearing a traditional white T instead.

Quality not as good as last years. Width at bottom of top causes top to roll upwards

Keeping warm in style

Yes, I recommend this

Loving the thermals from M&S and the colour choices. I have them in all colours now, tucked under other clothes to ensure I keep warm without the bulk. I often wear them on their own too. Recommended.
