Great leggings

Yes, I recommend this

These were really comfortable and fit well. I've got a pair of the heavier weight thermal leggings but I much prefer these - they feel much nicer on. I bought some more to put away for next winter!

NAVY LEGGINGS , LOVELY COLOUR , COMFY WAISTBAND

Yes, I recommend this

I buy these because they are so warm and comfortable. Waistband is thin and soft , is at waist height and doesn't feel restrictive. Much prefer navy to black which doesn't suit me as I'm not young.

So comfortable - perfect

Yes, I recommend this

Heatgen Medium Leggings have long been part of my regular wear wardrobe. These are perfectly wearable and so comfortable. The fabric weight and stretch couldn't be better. (The equivalent that I bought last year were far too thick and stuff). Had there been more pairs of these leggings available in my size to purchase in store or online I would have bought more; I'll keep looking.

Great for Winter

Yes, I recommend this

I have 4 pairs of these in different colours and wear them all the time in the winter months. I am a 12/14 and buy a 14 as I don’t like anything too tight. I do think that this latest pair are not as good quality as previous ones, they are thinner and not as fluffy on the inside.

Material bobbles quickly

The leggings are very soft and comfortable but they bobbled between thighs before the first wash.

So warm

Perfect to use as thermals under trousers and also as tights under a dress. Dual use, who knew eh?

Warm and snug.

Yes, I recommend this

I bought one and then I bought another ! as I found them comfortable and cosy for when it was chilly outside. I found them a little large for me in size 10 but maybe I should have got a size 8 however, they are not really baggy but they are also not tight. I like them as I hope you will do too.

Great Waistband

Yes, I recommend this

Very easy to wear. I have a stoma and the top of my bag sits on my waist and am always searching for "GOOD" waistbands. These leggings have just the right amount of stretch and a wonderful narrow and easy easy waistband.I will buy the thicker leggings in the autumn.
