Sleepsmart 37.5® Technology Temperature Regulating Down Alternative Duvet Insert

Construction

• Fill is made of 80% antimicrobial polyester and a 20% 37.5° performance fiber blend that eliminates allergen- and bacteria-driven odors for the Fresh Zone™ (dual freshness) experience.
• Our Fresh Zone™ technology and 37.5° fibers work together to prevent odor and eliminate bacteria-driven allergens in the fill.
• Double-needle-stitch sewn through box quilting prevents fill from shifting, with 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.
• 37.5° technology releases excess heat and humidity, preventing it from becoming trapped within your microclimate. Works immediately and continuously while you sleep to either trap heat when you're cold or evaporate excess heat and humidity when you’re warm. Moves heat away before sweat can form, minimizing swings in body temperature so you stay asleep longer.
• Body-heat activated performance provides comfort personalized to each sleeper's need for warmth.
• Sleepsmart™ is designed to work as a total system; its performance increases with additional Sleepsmart™ layers.
• Imported.
