About this style

When the temperature drops, beat the chill in our thermal long johns. Regular fit with an elasticated waist and cuffed bottoms for snug and secure wear. Functional keyhole fly opening. Our clever Heatgen™ technology uses an innovative fibre blend, helping your body to generate and retain heat so you can stay warm when the weather gets chilly. Brushback texture feels gentle against your skin, while supersoft seams ensure there's no chafing.

Thermal long johns

Yes, I recommend this

I bought these for my partner for Christmas, & he loves them! They fit snugly, they're soft, & they keep him nice & warm on cold winter mornings when lounging around in his dressing gown. He's even been known to wear them under jeans/trousers when out & about. They do leave bits of fluff around at first, but this reduces each time they're washed, & it's a minor issue. Recommended!

Very soft. Very cosy.

Yes, I recommend this

These long johns are in the warmest range of thermals. Despite that the fabric is quite fine. It does wash to be marginally thicker but still remains a lovely fabric. The fabric is also easy to wash. I don’t have a dryer so hung them on a rack to dry but the fabric was still nice. I did think the fabric was too thin to keep you as warm as they claimed but I have been told they are lovely and cosy. They also fit well. They were such a hit another set was purchased!

Excellent quality and value!

Yes, I recommend this

I had been looking for base layer pants from outdoor leisure shops for a while and was frustrated by the lack of "straightforward" choices. I had remembered a friend mentioning M&S and gave them a try. I was pleasantly surprised to find their range of base layers. They appeared to be exactly what i was looking for (including the open fly design) so I bought a pair. I have worn them twice and am most impressed. High quality, comfortable and excellent value.
