M&S' thermal tops have proven so popular with shoppers, they've racked up hundreds of five star reviews. Some people say the tops are SO warm, they don't need to turn the heating on when wearing them.
One five-star reviewer wrote: "Save on heating costs. Been buying Heatgens for years. Sadly, four 8+ year-old ones had done their duty - the lycra had lost its lycreness. Time for replacements! Lovely fabric that sits nicely underneath jumpers and cardigans without scrunching up. Much like wearing a second skin. Warm and lightweight and nice and long for tucking into trousers/leggings. Wash well and dry quickly. Wouldn't be without them."
Another said: "Once your body warms up with them, they form a lovely cosy layer, perfect for working from home without the heating on! Good amount of warmth for me but you may need a thicker pair if you prefer to be very warm. Lightweight and very comfortable so also easy to wear under a number of layers if wished."
Somebody else said: "Who needs the heating on with these? Blissfully warm under anything, nice long sleeves as well."
M&S' thermal offering doesn't stop at long-sleeve tops. M&S is also selling thermal leggings, which use the same Heatgen™ technology, for £16.
You can get a pack of two thermal M&S leggings for £25. The leggings come in the same colours as the tops, meaning you can mix and match.
