New Best Friend

Yes, I recommend this

Having purchased long sleeve thermals from M&S thought I would see if short sleeve crew necks were a thing, well glad I did, these are gorgeous, soft, bouncy, lovely fit and warm, quite pricey @£14.00 each but I loved it so much I bought another 2 all in black, washed one already and its lovely even softer v happy!

Heatgen™ Thermal Tops

Yes, I recommend this

The long and short sleeve tops from the Heatgen™ range are my absolute must-haves for damp and chilly days – no matter the season. They’re incredibly comfortable for long walks with my dog across the Scottish hills and perfect for wearing at work in air-conditioned spaces where the temperature tends to be lower. I have them in a whole range of colours, and they truly make a difference in keeping me warm without feeling bulky. The fabric is soft, lightweight, and feels great against the skin – it moves with you and keeps its shape even after many washes. Highly recommended – practical, stylish, and genuinely cosy. A brilliant everyday essential!

Winter Essential

Yes, I recommend this

Thankfully it’s not cold enough to wear yet, but I have the same in a vest and a I can’t live without it. The best thing it’s so discrete it easily goes underneath any clothing with feeling trapped in your clothes

Good quality warm top

Yes, I recommend this

I’ve many of the long sleeve versions and wear them regularly and this is just as great as they are. The only thing I would change is the neckline as I want to wear under thinner dresses its a little high for some but otherwise it’s perfect.

Excellent item. Only 1 minor problem.

Excellent item. Warm and light. I wish there was a low neck version. Only slight criticism is that it rides up from the waist due to the elasticity .

Great wardrobe essentials

Yes, I recommend this

After seeing similar tops on instagram I would never have normally purchased these but I’m so glad I did. They are perfect for under cardigans and under tops, also keep you so warm without having to wear lots of layers.

Bought in cream. Very comfortable, snuggly and you dont overheat. Top comes right down and covers your back. Buy your usual size. Just what's needed with this cold/chilly weather.

Very soft and comfortable

Yes, I recommend this

Ordered 2 of these for size after reading reviews. Not much difference between the 10 and the 12. Both sizes fit, so kept both as I was so pleased with the quality. They add warmth without being bulky and look like a t shirt rather than underwear so it doesn’t matter if they show when worn with low neckline. They have washed well too.

Cosy fleecy short sleeved tops.

Yes, I recommend this

I have several Heatgen Medium scoop neck tops and Maximum crew neck tops, so I thought a couple of these short sleeved tops would be useful too. They fit well, are cosy and comfortable, though I’ve not actually worn one yet. I love the crews necklines introduced this winter season.
