Warm

I bought these as my older ones needed replacing. They don't feel as thick as my previous ones and if you hold up to the light ,you can see daylight. I haven't worn them as leggings on their own but have wirn with skirt and dresses as thick tights. They keep you warm ,would recomend them in this cold weather

Great thermals

Yes, I recommend this

These are great leggings. They are thin enough to wear under trousers and are still so warm. They are washing well. An excellent buy.

ladies thermal heatgen leggings

I thought these would be useful to wear under trousers or a skirt. Not very happy with them as they aren't as warm as I'd hoped and tended to be baggy with a days wear. I couldn't return them as I used them, unfortunately. I bought some men's thermals and they were much warmer.

Not great quality

No, I don't recommend this

Thin and not like the leggings I’ve purchased in the past that didn’t need to be layered. Be more specific MnS!

Poor

No, I don't recommend this

Poor quality. I bought thermal leggings last year and they were excellent. This year, for the same price, I received poor-quality tights instead of leggings. Very disappointed and unlikely to purchase again.

Excellent under jeans or trousers. They are so comfortable and keep me warm . You do not feel over dressed or too restricted. Wash really well and dry quickly.
