I know it's the middle of a real bad winter but this would be ideal to put in with your winter duvet now to boost it a bit for the extremely low temperatures we are getting, and when summer comes (lol!) you will have a nice light summer duvet for the long hot nights.
This Fogarty 3 Tog Duvet is light in weight to keeps you fresh and dry on hot summer nights. The duvet has a 100% pure cotton cover filled with polyester hollowfibre and is non allergenic so is ideal for anyone who suffers from asthma or other allergies. It can also be machine washed for easy care.
Next cheapest i can see is £20 at Dunelm mill.
