Our exclusive SleepSmart™ bedding continuously adjusts to help maintain a climate of personal comfort at the ideal temperature of 37.5° Celsius all night long. Paired with the softness of down, this duvet insert gives you comfort and warmth that'll leave you waking up rested and refreshed.
Construction
- Shell is woven of 80% cotton and 20% 37.5° performance polyester.
- Innovative blend of 550 fill power White Down and 37.5° fibre provides enhanced thermoregulation.
- 37.5° activated carbon particles absorb odor molecules to keep your bedding smelling fresh.
- Sleep smart™ 37.5™ technology uses naturally derived fibres that work continuously to trap heat when cold or evaporate excess humidity when warm before sweat can form. Body heat-activated performance for comfort personalized to each sleeper's need for warmth, so you stay asleep longer.
- Sleep smart™ is designed to work as a total system; its performance increases with additional Sleep smart™ layers. High-performance properties last the life of the product.
- Double needle stitch sewn through box quilting prevents fill from shifting and has corner loops for easy attachment to your duvet cover.
- Allergen barrier weave is breathable yet resists allergens from entering into your bedding.
- 230 thread count.
- As you sleep, temperature and humidity build-up and become trapped in your sleep environment or microclimate, potentially causing discomfort. This design helps manage these factors, promoting uninterrupted rest.
- Imported.
Care
- Machine wash and dry.
