Heatgen Plus™ Thermal Long Sleeve Top is rated 4.8 out of 5 by 648.
Rated 5 out of 5 by from Brilliant! Extra warm version of Heatgen tops This is just as good as the other long sleeve Heatgen tops (which I'm a huge fan of), with the added bonus of being the "Extra Warm" version - the online description and name doesn't mention this. I did wonder why this was a little bit more expensive than the other version, but I ordered it anyway as the cream colour was out of stock in the other version. I was delighted to find that this was slightly thicker than the other version, which I sometimes find is not quite as warm as you'd expect for a thermal. This version keeps you toasty! It's still lightweight, but is just a little bit thicker. I'd say this has more of a proper thermal warmth than the other lighter weight version.

Rated 5 out of 5 by from Thermal Top These brushed Heatgen tops are SO cosy and warm! They do not take up much room under a jumper etc but add significant warmth. So cosy in fact, it will be difficult NOT to wear one under a top during the Winter!The BRUSHED vest tops are far superior in quality than the ordinary thermal vests. It is really worth spending a bit extra. I went up three sizes as I can't bear anything too tight. If you buy your normal size they WILL show every lump and bump! Not a good look I'm my case! I now have three and I will not be going back to wearing the non brushed ones I bought from M&S last year!

Rated 5 out of 5 by from Heat Gen Plus top in the Sale Ordered this online and picked up in my local branch. Have worn it several times and washed it. It washes very well. It is a lovely colour and I am able to wear it as a top. I have had lots of comments on it. Getting it in the sale made it really good value for money. I usually wait for the sale because the price is quite steep otherwise. I loved it so much that I got one for my daughter and also bought another two in different colours from M&S in Merry Hill sale whilst I was on holiday. The length is just right for me and the fit is comfortable.. It is very cosy gives an extra layer without bulk when it is very cold and is ideal on cooler days just to wear on its own.

Rated 4 out of 5 by from Very warm layer Ordered this as I wanted the usual thermal t-shirts you do every winter but in a cream colour. Was confusing on the website as there appeared to be 2 different thermal long sleeve t-shirts available in cream, one at this price and the other two pounds cheaper and the description of both appeared the same. The difference is the fabric thickness - this one is much thicker than a t-shirt material and VERY warm as the inside of the fabric has an almost fluffy finish. It fits well and is comfortable etc but is bulkier than expected if using as a layer under tops.

Rated 4 out of 5 by from Lovely and warm I couldn't of survived a trip to Norway without these tops. They have a brushed lining and are very warm and comfortable to wear. The sleeves are a bit long, I brought a size 6, but then I am only 4ft10. The only thing I will say is after washing them several times they have started to go a bit bobbly and I certainly couldn't wear them as outer wear which you could when new. Also around the neck folds over a bit after a few washes and doesn't sit as true as it once did (this could probably be solved with an iron!) They do not go in the tumble dryer but do dry overnight. If you feel the cold as I do, they are brilliant as thermal underwear, hidden out of sight!

Rated 5 out of 5 by from Lovely cosy top I have been buying M&S thermal tops for years to layer up in the winter. They are nice and long, so they show under a jumper to contrast or co-ordinate with the rest of my outfit. I bought this one in Berry, which goes well with all my other autumn/winter colours. I am a size 12/14, but I always buy these in a 16, as they are usually very clingy. I bought this one in a 16 and it is perfect for me. This top feels lovely to wear and is thicker than my others, which is even better. It would be nice to see it in more colours: a nice rich rust, or cinnamon, perhaps?

Rated 5 out of 5 by from My favourite thermal These brushed thermal tops are a must. So warm and versatile. The sleeves are longer than the old style which I love. Keep my wrists warm and I can pull them down a bit at the top of my hands for extra warmth. I wear mine on its own or over the thermal polo for work when it's very cold. This top moves with you. There comfy snuggly fit and stay in place but stretchy enough to move too. I won't wear any others. They're also long enough to to sit below the waist and stay put too. So glad these are back but better. Well done Marks. Please have them available every year. Excellent quality.

Rated 2 out of 5 by from Shrunk in Wash My teenage daughter and myself wore these in the recent very cold snowy spell. We did not want to take them off. They were lovely and cosy. We got bought our usual sizes and they were a close but not tight fit, so cold air could not get in. However, after just one wash they have shrunk and gone from a close fit, to a tight fit, so you are conscious of bending your back or elbows. The sleeves have shrunk about an inch too, so are above wrist length now. It is very disappointing. They were washed on a minimum wash cycle and not tumble dried. The unusual blackcurrant colour was lovely - so nice to get something a bit different. You could wear the top on its own.
