Heatgen™ Thermal Longline Top

I was delighted to find a LONGER LENGTH option in the thermal top section at m&s. I live in these thermal base layers from december to March and find the shorter ones riding up my body which is annoying and uncomfortable. Well done m&s for acknowledging that bodies are of different lengths as well as widths ! Please more colours next winter ! And a higher neck line option too would be great.

Warmer than expected, but still breathable.

I am planning a Scandinavian holiday next March, and needed more thermal underwear. I bought some in store several weeks ago. The title has now changed. Previously they were 'extra warm' which has a brushed lining. 'Heatgen' does not.

Really pleased with my thermal longline top, I'm reasonably tall but this is lovely and long in both the body and the sleeves. Perfect for layering under winter jumpers. Giving 4 stars instead of 5 as I have to agree with other reviewers on one point - please M and S could we have some more colours as well as black?

This is the best layering piece ever, being only 5ft 2, I love the long line which enables me to put a shorter top over it and my hips are still covered.

Would recommend this warming top, I love it. I’m an 18 and this size fits well, Very generous length. The material feels wonderful and it keeps me warm as toast. Will be buying more, leggings equally brilliant. Thank you M & S.

Really snug, extra long, covers my hips (I'm 5 feet 5 inches), arms really long which I like.

This top will be perfect for layering and is just what I wanted.

I wear these Heatgen tops as a base layer all through winter. They’re comfortable and cosy and I’ve washed previous ones many, many tines.

I am really pleased with this top. It keeps you lovely and warm. I find all your tops are quite short especially in size 20/22 so I bought the longline top which isn’t that long but just the right length for size 22. I am disappointed it’s only available in black. Come on M&S listen to your customers and bring it out in more colours.
