Feel and touch

Yes, I recommend this

The feel and touch of these leggings are lovely. They are much warmer than normal leggings, but are not chunky and unflattering. I would highly recommend whilst colder weather is still upon us.

Different to the grey version

No, I don't recommend this

i bought these black ones after buying the same in grey. They are quite a bit bigger although both size 8. Having worn the grey ones a few times I'm hoping these back ones will not bobble as the grey ones have.

Granddaughter loves them

Yes, I recommend this

I’ve not seen them as they were delivered straight to my granddaughter but she text to say she was keeping both pairs - I had ordered both of the thermal legging styles. These were the only grey leggings available. The thermal label made me wonder what they might be like. But if fussy teenager likes them, they must be good. Ordered the size 6.

Love these leggings so sift and cosy

Yes, I recommend this

This is my second pair. I am 5.5 and they come to my ankle. They are fleecy inside and warm. I wear them constantly round the house snd to the gym. Much better fur winter than my Nike leggings. Also have the top to match which is a cosy base layer. Good price.

Would 100% buy again

Yes, I recommend this

After reading the reviews about them being too short I went up a size. I am usually a 10 but went for a 12 and they are perfect, not at all short and are so warm and comfy! I wear them just by themselves or under trousers/tights as an extra layer. Not thin at all!

Lovely and Warm!

Yes, I recommend this

I bought these leggings to go under jeans when I walk the dog in winter so I've not yet tested them outdoors. However, they feel so warm and cosy, especially as they are brushed on the inside.

Very short!

No, I don't recommend this

The fabric and warmth is excellent (and I kept the matching top, so the garment quality wasn’t the problem) but they are so so short and have been returned. I’m so disappointed, as in the photograph, they clearly come down to the models ankles, and all I can assume is that she is the UKs only paid model who is under 5ft4ins!! I’m only 5ft8ins, and these came mid-calf. Have returned them and ordered the men’s (as my husbands ones were full length although not as nice fabric). Boo hoo.

Charcoal Mix Thermal Brushed Leggings

No, I don't recommend this

Very disappointed with material. When on not soft to touch and looks and like feels ribbed. Wish I got another pair pair the other year. Before the lockdown would have gone in store!!! Different material to that of the top and slightly different shad to that of the top: of which you can see the difference when both worn together.

Still comfy, but changed for the worse

No, I don't recommend this

I bought my initial pair of these a couple of years ago and they were my absolute favourite. They were the comfiest and warmest leggings I had, and I haven't been able to find something else to compare to them. As they were wearing a bit, I decided to buy some new pairs this winter and was very, very disappointed to discover that now they are several inches shorter than they used to be. I thought I had ordered a petite size by mistake, but it looks like this is the only length they sell and others have found them too short as well. I find it absolutely baffling as they're not really fit for purpose for keeping you warm when half of your lower leg isn't covered. I really hope they fix this, but until then, I will not be buying these again.
