A 4.5 tog duvet is the single easiest swap if you are still sleeping under a 10.5 tog all year. It is light and breathable, washes at 40°C and comes in single up to king, so it is the obvious place to start before you spend more.
The catch: 4.5 tog can feel too thin once autumn arrives, so you will want a warmer duvet to switch back to.

Look Into researches products from published sources: makers’ pages, retailer listings and regulators. We have not handled or tested these products, and a blank field means we have not recorded that figure yet, not that the product lacks the feature. Awards are Look Into editorial picks, not Amazon or third-party awards. As an Amazon Associate, Look Into earns from qualifying purchases; commission never decides a ranking.
