Great comfortable vests.

Yes, I recommend this

I couldn’t live through the winter without M&S heatgen vests. Having some short sleeved ones means they are versatile for when long sleeves aren’t needed or wanted. Great for wearing under dresses, shirts , sweaters. Soft and comfortable, and wash like a dream.

Not quite what I expected

No, I don't recommend this

Good quality but somewhat thicker than I expected; the sleeves are shorter than I imagined, but the real problem is the length. I am at 5ft 8ins tall and even for me the top itself is far longer than is comfortable. Disappointing.

Reduced Quality

No, I don't recommend this

Having worn the long sleeved versions for many years, I was keen to try this short sleeved version. Firstly I was taken aback by the thinness of the material, not what I was expecting. The top is easy to wear, but after a couple of days and washing, it didn't look great. Definitely not worth £9 each.

Warm tops for the winter

Yes, I recommend this

I leave been buying Heatgen tops for years and wear them every winter. This is the 1st time I’ve purchased the short sleeve tops primarily to wear under fleeces and find just as good as the long sleeves ones, I’ve also purchased them in cream and intend to get another pack in black.

Warm and comfortable

Yes, I recommend this

These are very useful to wear under jumpers without adding bulk. They are warm but not too hot. A good length too, which makes all the difference. They wash well and dry overnight. I bought some last year and they’re lasting well.

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.
