Frequently Asked Questions
Will a down alternative keep me cool in summer?
Yes—if it’s low-fill and paired with a breathable cover. Down alternatives can be cooler than thick natural down when the polyfill is light and the shell fabric (cotton percale, linen or breathable microfiber) allows airflow. Avoid high-loft or heavily insulated inserts for summer use.
What weight or 'tog' should I pick for hot nights?
Look for low-tog or low-loft inserts—there’s no universal number for polyfill, but choose an insert described as lightweight or all-season with thinner fill. The priority is breathability and thinness over plushness to prevent overheating.
How can I make my current duvet cooler without buying a new one?
Swap to a lightweight cover (cotton percale or linen), remove thick inserts and use a thinner all-season or summer insert, wash bedding regularly to remove sweat, and use corner tabs or clips to keep the insert flat so air can circulate rather than pooling in folds.
