Fabulous!

Lightweight and barely noticeable, these thermals do exactly what they are meant to - keeping legs warm and toasty without restrictions. Worn under both jeans and joggers!

Disappointing

No, I don't recommend this

I am not very happy with these long johns. They feel cold to the touch, which is a strange effect in something designed to make you feel warmer. I have only worn them a couple of times and they do help keep your legs warm, but they feeI odd. I am a bit annoyed that they came as a two pack, as I will not be wearing them enough to justify buying two pairs.

Poor quality not warm

No, I don't recommend this

These used to have some wool and cotton in them making them warm. This pair Has high %of acrylic in then which maybe good for carpet but not good form undergarments. The quality was awful to the touch so I returned them. MnS pls can you stop sacrificing quality .. stop reinventing the wheel.

Repeat purchase.

Yes, I recommend this

My husband wears these under his running trousers or shorts in the cold weather. He is very impressed with them. They are quite lightweight but very warm and he’s now bought a 2nd pack of them so he must like them!

Thermal underwear.

Nice comfortable material which keeps your legs warmer during the cold spells. Leg length is a little long but not a major problem. Repeat purchase.

Bought for a winter sports trip to Italy. Fit perfect with easy movement. The full test will come in February but similar to a previous purchase so expect them to be great.
