light weight, comfortable and effective
Yes, I recommend this
Excellent Product. Have worn them consistently with the onset of cold weather, and effectively banished the problem of cold legs. The long John are made of a light fine fabric which means they comfortable to wear. Essential winter wear

Excellent Heat Management
Yes, I recommend this
Not quite as stretchy as the thinner thermal trousers so if you like your ankles covered, go for a size up. Exceptionally warm, very comfortable and breathable. Would love to see these in dark red.

Very Comfy and Warm
Yes, I recommend this
I bought these for my husband, as he was playing outside in a band at a Christmas Market. They certainly kept his legs warm and he commented how comfy they were. I only bought one to test so will now definitely be buying another pair.

Not as warm or as good quality as they used to be.
No, I don't recommend this
The quality of these thermals is a lot less than it was 5 or 6 years ago. I include the vests also in this statement. I still have a pair from about 6 years ago and the difference in thickness, and warmth is like black and white. The old ones are much better. These new ones used to be much thicker, heavier, and warmer. Now, if they get any thinner they will be see through, and the “Warmest” isn’t particularly warm any more. The white ones used to have a vaguely yellow tinge from the wool but that has been non-existent for a few years. I’m sure the percentages of wool and whatever else is the same, but the problem is that they appear to have massively reduced the quantity of each item in the material but they haven’t reduced the price. They used to be nice and toasty. Not any more. There’s now a lot better quality elsewhere and sometimes cheaper. They need to go back and make them to the quality of 10 years ago.

Warm and cosy
Yes, I recommend this
These were bought for my husband and he was very pleased with them. The fit is true to size and he finds them warmer than his previous long John's.
Helpful?
Best ones for winter by far
Yes, I recommend this
Bought along with the thermal long sleeved top for my son He often works outside and living near to Hadrian’s Wall it can bit chilly to say the least 1 wear and I received a message ‘Please can you get some some more of these mum They are great’ My husband has the same in a smaller size so I can vouch for the fact they wash well with no shrinkage The grey marl sheds a bit from the inside so I bought black for them both as my husband wasn’t fond of his briefs looking like he’d been tarred and feathered That aside they are well worth the money The sizing stops at 2xx which is unusual fir M&S but as my son only needed that size in the top it wasn’t an issue I’ve also bought my granddaughter the ladies ones as she’s a painter and decorator and often works in large empty buildings with no heating
