2 Pack Heatgen™ Cotton Thermal Pants is rated 4.6 out of 5 by 34.
Rated 5 out of 5 by from Snugly fit I bought them for my husband to replace his old ones, exactly the same, in black. Nice soft thin fabric, snugly fit, good elasticated waistband keep them in place. Doesn't make his skin itch. Washes well, will last for ages. Pack of two is ideal in terms of saving and also practicality, when one pair in use, another in wash.

Rated 2 out of 5 by from Heatgen = light warmth (much to my surprise) I ordered these online expecting the most efficient longjohns when it comes to keeping me warm. Instead when I collected them in store and got them home I found from looking at the packaging that they were actually only light warmth design. I promptly returned them for a refund and upgraded to the 'medium warmth' variety. I can't comment on fit and other factors as I never took them from the packet or tried them on. M&S needs to make it clearer that 'Heatgen' only refers to the thinner/lightest warmth thermal underwear!

Rated 5 out of 5 by from These work and are very comfortable! Bought for my husband who feels the cold , I had to persuade him to try some longer thermals under his jeans. Pleased to say he is very happy with these navy blue modern looking thermal pants. Soft, Comfortable and warm. Value for money.

Rated 5 out of 5 by from Warm and comfortable Unlike some other brands, these pants are not baggy at all and fit really snugly. The material is smooth so it does not feel you are wearing them under trousers. They are also nice and warm. Ideal for when it is chilly outside.

Rated 5 out of 5 by from Happy Husband!! I bought these thermal pants for my husband to replace some older, thicker ones. We were surprised at how much thinner they are, but he is very pleased with them. He says they are warm and comfortable.

Rated 5 out of 5 by from Very warm & comfortable Husband wore these for work & is very impressed with the quality & extra layer of warmth they give him under work trousers. Not washed yet but as with all M & S clothes I’m sure they will wash well.

Rated 5 out of 5 by from First Class Thermals These thermals are a good fit, I'm 6'2, 205lbs, and Large were perfect. I had read that they were big-fitting so dropped from my usual XL to L and it was a good decision. The thermals are light, close-fitting, very soft and very comfortably warm, much nicer to wear than regular cotton thermals. I'll be throwing my old ones out and buying a couple more of these. They wash beautifully, not losing the 'new' factor like some fleece-type garments do but can't be tumbled. However, they dry quickly in a warm room or on a drying rack. I highly recommend these. I will be buying the matching vests too.
