Good fit and warm.

Yes, I recommend this

I normally buy M&S light thermal tops but these are a better fit and warmer for winter months. I also like that they are longer in length like the light thermal tops so they don't end up half way up your back when bending over.

Usually get the 2 pack lightweight. Have a thick weight, so opted for a medium warmth.

Warm and Snug.

Yes, I recommend this

Husband very happy with this. Much warmer than cotton tee shirts he normally wears. No chilling after getting hot walking. Nice long body and sleeves, not too fitting on the body. The dark green lovely colour and stripe effect which is different. Excellent value and well made.

Short sleeves - 15cm shorter than another M&S one

No, I don't recommend this

Bought one of these in-store, in small size, the sleeves are way too short, making it unwearable. Compared the arm length to the 2pk Heatge Light Thermal Long Sleeve Tops, bought at the make time, and they are the correct arm length, which is also a small size. I measured the arms side by side, and the the difference between them is quit unbelievable ,... this one's sleeve length is 15cm = 6 inches shorter than the other M&S thermal top!

With the weather getting colder I thought I would buy a thermal top to see if they really work. I’ve been super pleased at how cosy it is.

Brilliant warm top.

Hubby has 3 of these tops now. Essential for winter. Great top but the cuffs are a little baggy.
