Warmth Level
An incredibly light duvet, which provides an impressive warmth level (10.5 Tog) thanks to multiple layers of Simba Renew; the tiny fibres are combed into down-like clusters which keep you warm but also allow excellent air flow.
Both duvets feature the light, down- like clusters of Simba Renew but offer different levels of warmth: the 7 Tog duvet is suitable for milder Spring or Autumn nights, while the 3.5 Tog is better for warmer, Summer ones. Just join the two together for colder, wintry nights.
Temperature Control
The Hybrid duvet has one side of Stratos® heat control technology; this provides instant coolness to the touch and helps dissipate excess body heat.
Our Simba Renew clusters also help prevent overheating; the tiny, combed fibres allow excellent air flow.
Both the Spring/Autumn and the Summer duvet covers have one side of pure, breathable cotton combined with our Stratos® heat control technology; this provides instant coolness to the touch and helps dissipate excess body heat. The other side is a blend of cotton and moisture wicking Modal.
Our Simba Renew clusters also help prevent overheating; the tiny, combed fibres allow excellent air flow, while the added Modal fibres wick away any moisture.
