Tom's Guide Verdict In our experience, the Larke Nature's Blend duvet delivers excellent breathability and comfort. Made using natural tree fibre filling and pure cotton, the lightweight duvet is hypoallergenic and easy to maintain, since it's washing machine and tumble-dry-friendly. The biggest drawback is the luxury price tag; this duvet starts at £120 for a single size. But the added benefits, and quality sleep it helps you achieve, make it worth every penny.
