Great!

Yes, I recommend this

Have had pairs of these before. They are lovely and warm for the winter. Can be worn under outer layers or just as leggings. Very comfortable.

Fabric changed, not for the better

No, I don't recommend this

The fabric is very different to last seasons leggings. Felt much thinner and reading other reviews the fabric bobbled which is disappointing as I have older heatgen leggings that are no different from the date purchased. Another point is all of last season reviews highlighted the fact that the lengths are clearly for 7 foot+ tall women as they gather in folds at the ankles - not a good look!

Happy with the quality.

Yes, I recommend this

I like the weight of the Heatgen Medium Thermal Brushed Leggings. However they are enormous and I had to buy a second pair as I had worn the first pair before realising just how much too big they are! I am a fairly standard size 10 so obviously that's the size I bought. The smallest size you sell is an 8 which is what I bought second time around. These are really still on the large size but in desperation I bought them. At one time I had size 6,8,10 and 12 in your trousers. It really is time you standardised your sizing between one manufacturer and another.

Thermal leggings

Yes, I recommend this

Absolutely brilliant leggings can’t see through them at all, you wouldn’t believe that they were thermal, only fault is that they don’t come in short lengths, so iv had to have them taken up, ordering another pair

Great

Yes, I recommend this

Nice thermal leggings that aren’t too thick so will fit under my golf trousers in the winter. Haven’t needed to wear them yet but I’m sure the extra soft n cosy layer will feel good.

Not what I expected

No, I don't recommend this

Disappointed - expected these to be leggings to wear as trousers but they are like thick tights in quality so not substantial enough - will keep to wear under hiking trousers
