Amazing - these tops are my absolute favourites

Yes, I recommend this

I’m a long term fan of M&S heatgen tops - I have so many! They are such good quality and very versatile. They wash well and require no ironing. I reach for them almost every day in the colder seasons. However, you need to buy the right size. I’m an M&S 8-10 and I buy a 12, otherwise they are far too skin tight for my liking. I like to have the option to wear them alone, or under jumpers. The black ones are actually quite smart.

So useful - bought them for years.

Yes, I recommend this

Have several of these purchased years ago and they are still going strong. Invaluable for keeping cosy as a base layer in the colder months. Soft, nice and long but not at all bulky - they wash well and fit true to size.

Winter essential

Yes, I recommend this

Absolutely love this top. Low scooped neck means I can wear under almost any neckline. Lovely close fitting and long. Soft, thin, smooth fabric.

Happy addition for winter

Product good, not yet worn. Sleeves are too long to wear under a long sleeved dress. Good for jumpers etc.

A winter must

Yes, I recommend this

Lovely tops which are a necessity to me in the colder months. Go beautifully under my jumpers without being bulky. I have long arms and they are fit me fine. I am a 10 but went for the 12 so they weren’t skin tight. Will definitely buy them again.

Great quality and good value

Yes, I recommend this

I have been buying these tops from a well known Japanese retailer for many years but thought I would try these from M&S. The M&S tops fit much better around the neck although the sleeves and body are a bit long. I’m pleased that I made the switch as the overall quality is better. They also wash well and are better value. What’s not to like.

Excellent

Yes, I recommend this

These thermal tops are lovely and thin, but are very warm and comfortable to wear. The sleeves were a little long but easy to shorten.

Great layering top

Yes, I recommend this

I love these tops. I layer with them and they’re so light they don’t spoil the look of the top layer.

I wear these all the time, so comfortable and warm and lovely quality. I get one size bigger as they are quite snug.

Love this as it. Keeps you warm but at the same time it’s thin enough to wear under your clothes without being cumbersome you can also wear it on its own
