Hybrid™ Duvet

The Hybrid Duvet is finished with Simba's Stratos technology, a treatment that has been measured to keep the fabric surface up to three degrees cooler than untreated fabric, working through both an instant cooling touch and continued cooling across the night. It sits within Simba's wider bedding range alongside its mattresses and pillows and was named a Which? Best Buy in the 3-in-1 duvet category.

The cooling treatment is aimed at sleepers who tend to overheat at night, offering an alternative to standard tog-rated duvets that rely on natural fill alone for temperature regulation. It is covered by the standard 30-day accessories return window if it is not the right choice.
