Warm causal top

Lovely warm causal wear top . Bought it in black last year and wore it a lot. Fit is a bit on the tight side. I am normally a size 10 but had to buy the medium which is 12/14.

This top is really warm and very comfortable to wear. It's so soft and pairs nicely with the heatgen leggings or joggers

Useful Heatgem top, the open zipped neckline adds interest and functionality. I’m normally a size 16 but bought the extra large as I didn’t want it too tight.

Bought to wear under a waterproof jacket when walking. Really pleased with the quality for the price. Fitted, cosy, warm and looks great on. If you like a looser fit size up.

Love the style of this with the zip neck. Next time I would buy the next size up as the size I normally buy was a bit too snug.

Lovely warm and cozy top with zip and thumb holes to keep the sleeves down. Smart enough to wear as a casual top

I like the fact that this thermal top has a zip. I have bought the cream one as well. I buy lots of the scoop ones but they don’t cover the back of the neck.

Lovely colour, bizarre sizing

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

I am normally a size 12, so I ordered this in the medium size. I couldn’t even get into it! Just out of curiosity, I measured it before I returned it: 30 ins, or 76 cms!

Love these tops but the come up small.

Originally posted on marksandspencer.com (UK)

I love the Heatgen Max tops. Spotted this with the quarter zip front and had to try it. Purchased in Brown and Black in large. I am normally a size 14-16 but these always come up small and I like to have a little room in them. These were very snug fitting so had to send them back and order extra large which is mildly insulting but fits well. The are so comfortable, warm and wash really well.

This is thick and warm and great quality, I am a size 14 but I sized up to a large and it is perfect as I didn't want it too tight. We need more colours please.
