Great quality

Yes, I recommend this

Bought these for light exercise classes during colder months as not a fan of the sporty leggings. They are super comfy and not too thick. I have a few pairs of them they’re my go to leggings - I love this range.

Bought before

Yes, I recommend this

Bought them before and thought I ought to have one for every day for the winter. They fit well, are not tight, length is fine (I am 5ft 6in) and warm especially when you wear jeans in the winter. Wash well.

Good quality & Price shame about the fit

These are warm and comfortable but far to long both in the body and leg, this purchase is a smaller size but the same problem, otherwise I would have given 5 stars

Thermal leggings

Yes, I recommend this

Lovely and warm for cold weather wear. Would be too warm for me for as spring wear. I’m 5’ and these leggings are much too long for me. So I would have preferred a ‘short’ version. I decided to keep them as I will wear them tucked in boots or under jeans in very cold weather.

Bliss

Yes, I recommend this

I haven't had heatgen medium leggings before...so these are a revelation. Moderately thick, so very soft, plenty of give in the waist band (properly, my waist is too big for a size 12....but fit beautifully anyway, nice deep rise, neat ankles. And so warm. My house is only partially heated and these make a signigicant difference. Absolutely recommended.

Heatgen Medium Thermal Brushed Leggings

These are great leggings, I wear them under my trousers in the winter for extra warmth as I have osteoarthritis in my knees, they are of good quality and good value for money
