What is the duvet made of, will it keep me from over-heating?

The outer cover of the Simba Hybrid® Duvet is made from 100% breathable cotton.

On one side, Stratos® temperature-regulating technology is applied to the fabric (it's the side with the blue piping). Stratos® was inspired by the technology developed to keep astronauts a stable temperature throughout the extremes of space travel; for you, it will absorb heat when your temperature naturally rises during the night, storing it to release back to you when you cool down again. And the hypoallergenic fibre fill is also enriched with semi-conducting minerals that dissipate heat.

The Simba Hybrid® 3-in-1 Duvet or should we say duvets, arriving in a reusable non woven fabric bag, there are 2 duvets, a 3.5 tog summer duvet for the warmer nights and a spring/autumn 7 tog duvet. For the chilly winter nights, easily clip the 2  together to create a 10.5 snug and cosy 10.5 tog duvet. 

The Stratos® temperature-regulating technology can be found in the Simba Hybrid® 3-in-1 Duvet along with Simba Renew Clusters - Super-soft, sustainable Simba Renew clusters with durable, moisture-wicking Modal fibres.

So whether you run hot or cold, our duvets have you covered.
