Beautifully soft and comfortable thermal wear!

Originally posted on marksandspencer.com (UK)

Lovely and soft. I bought a size 14 and I’m just under 12stone and 5ft 6” so 14 is a lovely close fit. My only issue is the zip has been seen really badly so when I zipped it all the way up it got stuck and took mr a good hour to undo it! Poor quality sewing. I would however say the shape of the collar is extremely flattering - love it!

Nice top but runs very small - I’m a size 12 and couldn’t physically get it on.

I buy these tops for the purpose of keeping cosy in the UK's unpredictable weather. They're smart too which is a bonus.

Loving this line of Heatgen thermal tops. They fit tight so great for layering. More colors please and I’ll buy the whole line I enjoy them that much!

Absolutely tiny. Probably need to size up two sizes. Now on sale so no chance to exchange.

Smart Comfortable Top

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

This thermal top is well made and extremely warm. I love the style and, as previous reviewers have said, it is on the small size. I am a size 8, this size was snug, I then order in size 10 which was more in keeping with the photo shown. If you an in-between size I would definitely go up a size.

Purchased as an addition to my collection of thermal tops for a trip to Norway in November. However, already been in use due to the weather here so, I can say with confidence that it does its job. Quality is good although everything recently seems to have long arms..unless mine are getting shorter!

Not great value

Originally posted on marksandspencer.com (UK)

It’s OK, but the fabric feels thin and cheap, and not very well made. Zip is lumpy at the bottom, and collar too big. Am keeping it solely for the thumb holes- such a rare find!
