Very comfortable and warm

Yes, I recommend this

I am very pleased with this thermal top. It is soft against the skin. I'm tall and found the length of this to be great, it doesn't untuck leaving you with a cold band at belt height. Glad I made this purchase.

Warm and Cosy.

Yes, I recommend this

Better than all the other base layers I have. Snug fit feels warm and keeps out all those winter draughts. So good I only need one base layer instead of two.

Not in the shop

Pity is that this item,colours and type was not available in my local shop. Online shopping is not my choice, but I needed this item and the shop does not display it for purchase. Having said that it is a very good product and does what you would expect it to do.

Great quality & thermal properties

Yes, I recommend this

I bought these for my 90 year old mother who is fearful of the cost of putting her heating on. Perfect for keeping her warm during this cold spell & far more effective than the ladies thermal vests. She is so pleased she has asked for more!
