Soft cosy material

Yes, I recommend this

Bought these for my husband to use when he plays golf. They are a nice snug fit and soft cosy material. I ordered size Medium as his previous pair that size. But he normally wears size large in boxer shorts.

Fit high, not as warm as hoped

Yes, I recommend this

These fit very high around the waist. They do not feel as warm as i had hoped, replacing some Damart long johnd which were warmer Not bad for the price.

Quite snug fit at waistband

Good quality but even although I'm a size 10 (I'm a Postie!) long johns were a bit tight at the waistband.

First time thermal user wish I'd bought years ago

Yes, I recommend this

First time thermal user, a godsend, not that anyone sees them but they look like leggings when on, stop the wind going right through you. under. Work very well to keep warm when outside for periods of time but also not too unbearable when inside. Bought another set. Happy with the quality and feel against the skin. Wish I had bought years ago.

Good quality and fit

Yes, I recommend this

Very soft and light but super warm and unisex. Longer than the women’s so great if you are over 32” leg. I am skinny but I also got them for male partner and they were comfortable on his rugby legs.
