This is so warm especially under sweaters during the recent cold spell. I was lucky to get it when M&S alerted me as being back in stock! Hope there will be more of the patterned ones going forward in the non fleecy too. I have some getting worn out from past years and recently just plain ones

A must have for those that hate the cold

Was so happy when my size was restocked online. I'm a sucker for leopard print. Stylish yet keeps you nice & toasty. I've worn it loads already during the baltic snow weather we've had recently.

Lovely top

Great top. The colour is more purple than shown on the website, I think it would be nicer if it was more brown but the fleece lining is lovely and soft.

GREAT QUALITY AND WEARABILITY OPTIONS !

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

This must be the best product sold in M&S. I own the whole range: I wear the finer ones in spring & summer and the warmer ones in winter and I combine them - playing with the colours in blouses, cardigans, dresses or simply on its own - just fantastic! I wish for more colours, specially the royal blue that is no longer on sale but I live in hope as I do love to dress well!

I love love love the pattern of the fabric. This design works so well for thermal top, as the usual ones can be a little uninspiring.

Disappointing fit

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

Good style/pattern but far too long in the body to be tucked into jeans etc. material is too thick and not breathable. The fit on these has also gone very small. I returned and the search sadly goes on!

Always the best

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

They are fantastic, and I've been slowly collecting all the colours. ​My main advice is about sizing: I am a standard UK 10, but I size up to a 12 or sometimes even a 14. This allows for extra length in the sleeves, which is exactly what I look for in a comfortable thermal. The amazing thing is that even going up one or two sizes, the tops still fit me perfectly—they remain close-fitting and smooth, making them ideal for layering without feeling bulky. A quality product that holds its shape!

I think this thermal top is really lovely and soft and it’s very to nice to wear. I’d like another one but I will size up next time so it’s not so skin tight.
