Good base layer for colder weather

Yes, I recommend this

I have bought these thermal leggings for a number of years now as I am out with the horses & sheep on our smallholding in all weathers. They are perfect to wear under work trousers as very thin but give you that extra layer of warmth.

cosy legs

Yes, I recommend this

I love these thermals! They fit nicely are not bulky and give a nice cosy warmth. They are a repeat purchase as I want to always have clean ones to pop on and be cosy. The fabric is soft and feels lovely against the skin perfect!

Lightweight but warm.

Light weight thermal leggings which are long enough! They are great under jeans as the temperature drops.

Very happy with these!

Yes, I recommend this

These are great, I already had heatgen maximum leggings which I really like but I wanted leggings in a thinner fabric that are more comfortable under trousers. These fit the bill, they are very comfortable, have a good stretch and definitely keep my legs significantly warmer. Great buy!

Too thin!

No, I don't recommend this

I think these thermal leggings are not as described. They are very thin and almost see-through and are more like footless tights! I think this should be clearly stated in the item description.

Best leggings

Yes, I recommend this

I can wear these all year long, they are light yet covering, flexible yet sturdy, I can't find anything comparable, and I have tried.

Absolute Winter Necessity!

Yes, I recommend this

My standby garment for wearing skirts in winter, I have them in black and navy. They are soft, stretchy and comfortable and hands down better than tights. They are surprisingly warm, and mean I can wear skirts and dresses at any time of year. They can also be worn under another pair of trousers for an outdoor event in the winter time. Recommended

Thermal leggings

No, I don't recommend this

The leggings were very thin to the point of almost being see thru. I was dissappointed at the thinness of the fabric. Also i don't feel they were really thermal either. Over priced and poor quality.

Will they be warm enough?

Yes, I recommend this

These are sold as thermal leggings. They are very comfortable but the fabric feels quite thin. The weather is not cold enough yet for me to be able to assess how warm they will be.

Very thin!!

No, I don't recommend this

This pack of thermal leggings are extremely thin and does not have much stretch. See through and in my opinion extremely poor quality. I would have returned but the return process is very difficult as I do not have a printer and too busy to get to store. Overall Very disappointing!!!

Disappointing

No, I don't recommend this

Very disappointed with these. Very very thin material and can see through to my skin. No warmer than normal leggings. Don’t even deserve 1 star.
