This is a luxury polycotton 4.5 tog double bed size hollowfibre duvet. The duvet is made of up non-allergenic hollowfibre, it is constructed in a channel stitch to help evenly distribute and hold the fibre filling and a cotton blend fabric is used to finish it. Each strand of hollowfibre is perforated allowing moisture to flow away from the body and also allow an easier airflow as you sleep. This would make an ideal package for the Spring/Summer nights. The products is carefully made in the UK.
