Great thermal/ski gear from M&S

Yes, I recommend this

The thermal range is great for home and away. I have now had to buy for my daughter who lives in the French alps and who is recommending to all her friends and colleagues there!

Purchased for my elderly mother

Yes, I recommend this

My mother has numerous tops in various colours, she find them comfortable and they keep her warm. If she goes out it is a base layer or she wears them under a cardigan at home. Good quality, wash well, highly recommend.

Very warm top!

Yes, I recommend this

I sent up one size for this top.. Very glad I did as my ordinary size would have been a bit tight. Having said that it is a very warm top and I shall save it for a very cold day!

Great warmth

Yes, I recommend this

I already have the fabulous long sleeved thermal and this gives me an alternative when wearing tight-sleeved sweaters. I just wish the neckline was lower so it didn’t show

short sleeve thermal

Yes, I recommend this

i have several long sleeve thermal tops from m&s but this is my first short sleeve, decided this might be better under a cardigan and its perfect,the crew neck is a good fit round the neckline,no gaping,normal size is 12 but i prefer a 14 in thermals for a bit of extra room,very easy to wash and dry.

Denim shirt

No, I don't recommend this

Denim shirt had baggy sleeves- the cuffs were loose and they would not turn back neatly.
