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 for winter

Yes, I recommend this

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.

Not as exoected

These garments are footless tights not leggings. The fit is generous and they are easy to put on but are certainly not thermal and definitely not leggings. I have thicker tights! They are so thin you can see through them and have no weight or warmth, I wore them out as leggings and my legs felt, and looked, as though I had 60+ denier tights on. £25 for 2 pairs of opaque tights is not what I call value for money.

Great addition for the winter

Yes, I recommend this

I purchased these for the first time because I pick up my granddaughter from school each day. These are perfect for under my trousers or even my maxi skirts when I’m wearing them with knee high boots. Some reviews complained they’re rather thin but this makes them perfect for my purposes as they’re cozy without adding significant bulk to my outfit.
