Great value leggings, fits true to size

Yes, I recommend this

Great for under dresses/skirt or under trousers when it's very cold. They are thin, but I prefer this as they are quite warm as they are. I am 5'3, and they go down to the bottom of my ankles, but are not unmanageably long.

Lightweight warm and effective. Highly recommend.

Yes, I recommend this

I was surprised by how thin and lightweight the leggings were!! Not what I was expecting at all. But, worn underneath another “ordinary” pair of leggings, they were surprisingly comfortable and very effective at keeping me warm during our recent cold snap. So a great success and I highly recommend.

Fairly Warm and Comfortable Thermal Leggings

Yes, I recommend this

Good as a warmer substitute for tights or under clothes, but poor as just leggings as very thin and see through material, so you'll need a longer top and/or coat to cover your bottom!

Just the job!

Yes, I recommend this

I'm really pleased with these. As the weather continues to be unpleasant, I needed medium weight leggings to add to my lightweight and heavyweight collection! They fit beautifully, are easy to wash and tumble dry, and are also very comfortable.
