Annie_11 Lovely warm layer Lovely thick thermal layer. I size up in these so the waistband isn't too tight and despite this they always stay up and are very comfortable. Perfect for beside the football pitch, bit too warm for walking in.

JG17 Warm and comfortable Very comfortable and a generous length. Lovely and warm for yoga classes.

Juleskev123 Keep warm Absolutely perfect for these cold days. Great with a pair of boots

lovejeggings28 Warmth These leggings are so comfortable and with the fleece it makes them even better for the cooler months.

Yve 2 Warm. Just the job for staying warm and relaxing at home,and not baggy good fit,size 16.

Coriander39 Winter leggings I find them very cosy. I like the colour. Fits well

jamboys Thermal leggings The leggings are a good fit but perhaps could a little bit thicker

Eastbourne Sam Better than a pair of thick tights! I was pleasantly surprised by how comfy these are. I bought them for a trip to Norway next Spring and have tried them already to see how good they are. Happily they keep me comfortably warm. I even prefer them to tights! No bulkiness, bunching or baggy knees. Very happy.

haz1234 Very warm and comfortable I love this product. It's very warm and comfortable and I'm planning to get another 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.
