Warm and cosy leggings

Warm and cosy leggings. Fit was good, went for my normal size. They are a little long in the leg though. Very happy with them. Would definitely recommend.

Cosy and warm

Yes, I recommend this

I have a house that's cool in summer but chilly in winter, even with insulation and double glazing. Added to that, following a knee op I hadnt been as mobile as normal, but these fleecy leggings have kept me warm and fit well under trousers.

nice leggings

These leggings are lovely and warm. my only moan about them would be they have gone a bit wobbly all over and ive only washed them twice. I don't use softener and they didnt go in the tumble dryer, so I assume it must just be the nature of the fabric.

Roasting!

These are great under trousers in the winter and mean I can make my electric heating minimal.

Too Long

No, I don't recommend this

Nice leggings but far too long. I’m 5’ 4” and I had the choice of wearing them over my feet or suffering with Norah Batty tramlines round the ankle, knees or bunched up in the groin!! Shame as I would have kept them if it had not been for the length.

Absolutely love these thermal leggings.

Yes, I recommend this

Absolutely love these thermal leggings, so warm and cosy. They fit like a glove and don’t feel bulky. So far the quality seems good.
