This Hollowfibre 4.5 Summer White Tog Duvet is filled with polyester hollow fiber and surrounded by a soft touch microfibre cover to create a cozy and comfortable duvet. It balances slight warmth, weight, and loft so it’s lightweight even at higher togs, for a great night’s sleep. As a synthetic duvet, it’s non-allergenic, meaning there's nothing in it that could cause allergic reactions, which is great for peace of mind and essential for allergy sufferers. Being a 4.5 tog duvet, it’s an ideal option for summer and spring, or for those who prefer a lighter duvet. The luxury microfbre cover feels wonderful to snuggle up into - it gently wraps around your body so you can be cozy and still move freely through the night
