Know before you buy
This is specifically designed as a 'winter weight' insert with extra fill, making it ideal for cold climates or chilly bedrooms. If you tend to sleep hot or live in a mild climate, it may be too warm for summer months.
No, the stitch-through box construction creates individual pockets that keep the down evenly distributed across the entire insert, preventing cold spots and clumping.
Yes, it is machine washable. Use a cold, gentle cycle and tumble dry on low heat to maintain the loft and integrity of the down.
Fill power measures the loft and insulating ability of the down. A 600-fill-power rating indicates high-quality, resilient down that provides excellent warmth and a plush, airy feel without feeling overly heavy.
This insert is slightly oversized to provide a fuller, more luxurious look inside your duvet cover. While it will fit standard covers, the extra dimensions help it fill out the corners for a more inviting appearance.
The shell is crafted from 100% organic cotton that is specifically woven to be 'down-proof,' meaning the fabric is tight enough to prevent the down feathers from poking through.
