Most of the year: use the Spring/Autumn duvet (grey binding, 7 Tog),
Warmer nights: use the Summer duvet (blue binding, 3.5 Tog),
Extra chilly nights: snap the two duvets together for a thermal value of 10.5 Tog.
Our cotton provides an excellent fabric base for our innovative Stratos® technology. So you get the breathability of quality cotton as well as active temperature regulation.
It’s a phase change technology, designed to go above and beyond to regulate your temperature while you sleep. It works a little bit like the ozone layer, which keeps the Earth’s temperature in check by absorbing the excess heat from the sun. If you get too hot during the night, Stratos® absorbs and dissipates your body heat to cool you down.
You'll know which side of your duvet or pillow is the high-tech one because we’ve added a hexagonal shaped pattern to the side with Stratos®.
