Lovely

Yes, I recommend this

I’ve had a black one of these for many years and it’s about time I replaced it, so bought this double set. Lightweight and wonderfully warm, I love these tops. Ideal for layering as not too bulky, and the added sparkle makes them perfect for evenings out

Thin but useful

Yes, I recommend this

Liked sparkly tops but thinner material than expected. Decided to keep as weather milder more often than very cold but still need thicker style for cold frosty occasions, hence 4stars.

A nice under layer

Yes, I recommend this

Enough heat even although being thin material gives a smooth under layer.

Great sparkle layering top

Yes, I recommend this

Nice top for under layer. Sizing came up smaller than usual. I returned my usual size 10 for a 12.

Glamorous thermal tops

Yes, I recommend this

Bought a 2pk of heatgen tops years ago black and red. They’re in holes now but still wearable but I thought time for some replacements. Was delighted to see M&S still do them only black and grey which I’m happy to have the change from red. They’re comfortable, warm and have that touch of glamour which makes you feel like you’re not wearing frumpy thermals. I love em! They are worth the money as they last for years! Thank you M&S for keeping up with your good quality favourite items 🙏🏻 love M&S ❤️

Love these

Yes, I recommend this

Love these tops. So comfy and just the right amount of warmth. Really sad you can't buy them individually and that more colours aren't available in this thin heat gen top

Lovely but come up snug.

Yes, I recommend this

These tops are lovely but they do come up a bit snug , I’m a size 12 and always order a size 16 which are still fitted so for a more relaxed fit could do the size 18 , I don’t mind them snug as they are normally worn under something.

I have worn both of these at evening events - they are so warm and pretty. They really kept me warm despite a cool and draughty venue.

Sparkly thread

I've had a few of these thermal tops in the past. The tops are really warming however these are sparkly which does make them a little itchy. I've not had any issues with it but something to be aware of.

Cosy thermal vests.

Yes, I recommend this

Nice and slinky under a top layer. Come up small so I had to take thermals 2 sizes bigger than normal. They wash well.

No, I don't recommend this

Much too small fir a true 12. Which explains why no 14 or 16 available. All sold out for weeks

Good classic winter warm layering

Yes, I recommend this

These are great value, double pack and a bit blingy too. True to size, nice extra warm layer without being bulky. I bought two last winter, wanted another set to have enough to wear during the week. I took these back however, realised I could do with some fine polo necks to layer so bought a twin pack online instead.

Love these tops

Yes, I recommend this

I have quite a collection of these purchased over the years, these will be lovely to wear in the evening on holiday, also perfect with a suit. This pack is the only one with different colours, I like the black polos but I don't want two! With M&S quality they would outlive me! So come on M&S give us some variety. As others have said fit is on the small side, I am often a 6 but opted for size 8

These are great tops for thermals overall

Yes, I recommend this

Get the job done and quite stylish. My one thing is the sizing. They’re very tight in the body and too long as well. I’ve got a long torso so would be very long on someone with the opposite body type.
