Great Quality & Perfect Fit

The Heatgen Medium Thermal Scoop neck long sleeve sparkle top is very comfortable and keeps me very warm from the moment that I put it on. I have bought another two in plain black and one in navy. I have told my friends how good they are. Always Great Quality & Perfect Fit,

Lovely warm sparkly thermal top

This is a lovely cosy top and it’s smart enough for my daughter to wear under her work t-shirt as her work gets awfully cold. The sparkle makes it feel a little fancy and feminine. The is a repeat purchase to replace an older one that had earned its worth.

Wardrobe staple with a bit of pizzazz

Fits well, longer length great for autumn/winter. Warm to wear, has a subtle sparkle so a bit different and easy to wear as a top layer

Bought these as an undergarment. Quite thin material but still cosy.

This top is very nice I was hoping to get the non-sparkly scoot neck ones but they don't seem to make them anymore so I thought I'd try this one and it's very nice, so I'm quite happy I will be buying more, however I would say bring back the all the other non-sparkly ones in all the colours please I like the chocolate brown colour and the black

You wouldn't know this is a thermal top!

Originally posted on marksandspencer.com (UK)

I bought this top (with shiny flecks in) because it is warm and does not look like a thermal top! The material is smooth and not a traditional thermal look. It is really comfortable to wear and I love the scoop neckline. The sleeves are nice and long too.

Pretty much a staple for me in the cold weather. I've bought 3 this winter in different colours. I like them as a base layer and the black one with sparkles jazzes up a simple outfit.

Subtle Sparkle

Originally posted on marksandspencer.com (UK)

I have a number of these thermal tops which I generally wear as a base layer. This one deserves to be seen more as it has a sparkly thread. I wouldn't wear it on it's own as it's clingy and reveals all lumps and bumps but I wear it under a low cut top and also under a sleeveless top so the sparkles can be seen. So it keeps me warm while adding more style and a bit of shimmer

Lovely brushed finish inside, making this a warm top to wear. Fun sparkly finish, but it's a shame it comes in so few plain colour choices for everyday wear. How about adding in a lovely bright Christmassy red, holly leaf green, sunshine yellow, cornflower blue etc to widen the range ?

Love the warmth of this figure hugging sparkly top. Smart but also casual. Great quality too. I keep going back to buying this one, it is so comfortable.
