      For my husband - his 3rd set

      He is a big fan of these pyjamas so I got us his and hers sets for our anniversary.

      He is much sweatier than me and whilst mine haven't worn out, his older ones have. So he is glad for the new ones.

      Brilliant

      This is a comfortable, lightweight top. Although light it is warm and soft and helps me get a good nights sleep. I love that it uses natural components and not made in PRC. I really like this item.

      Not warm at all

      I was looking for some warmth in my night suit but if feels cold. Not sure what wool is used. Waste of money for me.
