On those cold winter nights we all want to stay warm, so this bamboo fibre cover will help to keep the heat in. The bamboo fibre used in this set is more breathable than regular cotton which gives better temperature control depending on the season. It is also 4 times more absorbent than cotton so it'll keep you warm in winter and cool in summer. The natural anti-bacterial agent that is found in bamboo helps to keep the cover clean, and it's hypoallergenic so it is also suitable for sensitive skin. You'll feel incredibly comfortable with the 400TC duvet cover wrapped around you which will ensure you will get a good night of sleep!
