If you’ve ever struggled to find ski thermals that keep you warm without feeling bulky, we’ve got a game-changer for you – read our thermals review below.

our thermals review – What Makes Heatgen Thermals Different?

The Heatgen™ range from M&S is all about maximum warmth in lightweight fabrics. These fleece joggers are slim-fit with a soft brushed lining, so they trap heat without the heavy, stuffy feel of some thermals. They also have pockets (yes, actual pockets in thermals!) making them practical for everyday wear.

Why We Recommend Marks and Spencer Thermal Joggers

We’ve tried out loads of different ski thermals, but without a shadow of doubt, these are the best. Here’s what we noticed during regular wear, commuting, outdoor time, or layering under outerwear:

Easy care (within reason)
The care instructions are straightforward (wash at 40 °C, no tumble dry). As long as you follow them, the fabric holds up well over time.

Warmth without bulk
Because of the thermal fleece construction, these joggers warm you up without making you feel like you’re wearing multiple thick layers. You can still move, bend, and sit comfortably.

Stretch for comfort
The elastane content means you don’t feel constricted. If you’re doing errands, working from home, or even going for a gentle walk, they move with you.

Practical design
The hip pockets are a nice touch — you can carry small essentials (keys, phone) without needing an extra bag. The slim cut gives a sleeker silhouette under other layers.

Good value for quality
At around only £25, these joggers are an amazing price for what you get: a premium blend, solid build, and reliable performance in colder months.

Versatile layering piece
These joggers can serve multiple purposes: as stand-alone loungewear, under shells for hiking or walks, or under trousers when it’s bitterly cold.


Final Thoughts

We don’t often rave about thermals, but these M&S Heatgen joggers are the rare piece of winter kit that deliver comfort, warmth, and practicality all in one. Whether you’re staying home, heading outdoors, or travelling with family, these joggers are 100% worth the space in your suitcase. Our apres ski, is often just chilling in the lodge wearing these best thermals.
