Super warm

Sooo warm. Quite fine but I no longer feel the cold with these tops and they can be warm without looking bulky underneath tops or dresses.

I have been trying to order these for some time and was lucky enough to grab four pairs in black they are so snuggly and warm and as a tall woman 5 9 inches they are long so all in all I think they are brilliant. Just one footnote to the buyers next year you need to order a lot more as these have been very difficult to get hold of

These leggings are awesome! They are so warm, wash really well and come up higher around the waist than most leggings. I adore them!

Amazing, wash great almost dry following spin.

Had thermal heat gem max for several years both leggings and tops, top I’ve had vest type, plus long sleeved light and med all of which I wear either under heatgem plus fleece lined tops lovely and cozy, leggings indoors on their own or if rather cold then under jeans or trousers. Need to buy next size up for top layers but under ones either own size or one up. Some times buy one of each then take back one not wanted on first time buying each year. Great items though.

The perfect house trousers / pyjamas

Originally posted on marksandspencer.com (UK)

Perfect for someone who really feels the cold as I do. Satisfyingly thick, soft and super warm. A good length, they wash well. I just wish I could buy a second pair, ideally in navy, but they’re always out of stock online (and were never sold in my local store at all).

Thick and warm

Originally posted on marksandspencer.com (UK)

Really thick and warm, thicker than I expected so I haven't worn them yet. Waiting for the really cold weather . I tried them on under my jeans in case they were too thick and bulky but all was well so I kept them and looking forward to the snow.

Love this thermal leggings! I used this as a base layer under my joggers on our holiday in Iceland (November) and it was just what I needed. Enough to keep me warm day or night.

These tick the box on every level - warm, comfortable and can can be worn inside the house or out for a walk. Easy to wash and take care of. Wish there were more colours. Waiting for more to come into stock so I can buy more…

Possibly the best most affordable fleece lined leggings I have ever come across. I feel the cold, I live in the Scottish Highlands, these layered up keep the cold at bay. Also great for lounge wear inside, bonus!
