The main problem I found was the part left uncovered by the thermal wear - eg my hands - which started to get cold as I typed away while the rest of me was staying pretty warm in the layers. Breej Warm, comfy Extremely warm and comfortable and great fit. I’m a size 12-14 and the 12 was perfect.

haz1234 Very warm and comfortable I love this product. It's very warm and comfortable and I'm planning to get another one I added an extra jumper layer, but I caved in by 2.30pm and put the heating on for an hour to warm things up a bit.

Apz Heatgen These are very lovely cozy and warm. I don't think you can be disappointed with this one. westendgirl507 Heatgen (trade mark) Thermals for women I have had no great misgivings about thermal undergarments previously bought at M& S but Heatgen is revolutionary in the best sense. Light as a feather and breathable. Perfectly designed as the essential first line of defence under Autumn/ Winter clothing. Well done to M &:S for ensuring (last time I looked online) that all sizes remain available. They are all really easy to wash in a standard washing machine, and as they're created with stretch they are also particularly comfortable and practicable items to have at hand.

She wrote: "Overall, I was pretty impressed with the M&S range - particularly the Heatgen items with their super cosy fleecy interior. All of the items I felt offered a reasonably-priced way to try and keep yourself warm this winter.
