Exactly what I wanted

Yes, I recommend this

I wanted a thin layer to go under jumpers, and for the neckline not to show, these are perfect. I ordered 2 sizes up, as I wanted more of a t shirt fit than a tight fitted thermal, being the coolest of M&S 3 thermal levels, it’s not too hot under my jumpers. Perfect!

Light soft and warm. Great quality price

Yes, I recommend this

Excellent. Very light, soft, warm enough. I like short sleeves below a jumper. Nice even as a fitted t shirt when I need to remove my jumper if too hot inside. Great quality price. More colors as navy would be great.

Thermal Vests

They are excellent value and comfortable and quite cosy. I just wish I could have had a higher neckline, although I did know they were scoop neckline when I bought them. Would recommend and I also have the long sleeve warmer ones which are good when it’s very cold.

Extra layer of warmth

Ideal thermal wear to use in the Himalayas. An extra layer will be extremely important.

Practical and comfortable

Work under most necklines. Comfortable way to add extra warmth. Wash well. Only downside is tendency to ride up

Very pleased with these tops

Yes, I recommend this

I'm very pleased with these thermal tops. They are comfortable and warm and fit very well under my dressier tops. I bought black and white tops but would love it if M&S also sold them in a neutral beige colour.

Great value under-T

Yes, I recommend this

Good fabric but a little too clingy for my taste. Because of that, better to wear under other clothes. Great value
