It\'s the clever technology behind our climate control duvets that makes them extra special. These duvets blend our Smartfil technology with a special ingredient called Modal, which is derived from natural wood pulp and exceptionally breathable. Modal helps to wick moisture away from the body, allowing you to sleep in total temperature-controlled comfort and wake up feeling refreshed. By investing in a temperature-regulating duvet, you\'ll be investing in a calming and restorative night\'s sleep. Pair it with the Breathe Pillow (sold separately) to keep your cool from head to toe.
