Not all sleep is created equal. Not down is created equal, either. Every Peacock Alley down duvet offers you the finest European white goose down fill that is responsibly sourced, sterilized using the Ultra15 Clean™ process, then wrapped in a 400 thread count cotton sateen down proofed cover that feels incredible. Our year-round weight at 650 fill power gives you a light layer to work with so you can customize your very own sleeping environment. All of our Down products feature down that is responsibly sourced and meets or exceeds an ultra-clean rating.
