The luxurious WHITE DOWN DUVET by DOWN UNDER BEDDING is designed for premium comfort and restful sleep. It is ultra-soft and extremely fluffy. Finished & Filled in Canada with 550 lofts white duck down, providing excellent insulation.

The cleaning and processing of the down are done to the standards of the Down Association of Canada, making it 100% hypoallergenic. The 289 Thread count 100% cotton down-proof outer shell prevents the down from leaking out and is remarkably soft, breathable, and hypoallergenic to ensure a clean and healthy sleeping environment. 

The baffled box construction keeps the filling securely inside the duvet, provides maximum loft, and offers an even thickness throughout the duvet for consistent warmth. This Hungarian White Down Duvet is designed with corner ties to easily attach to a duvet cover to hold the duvet in place. 

All-Season Comfort

This premium quality duvet provides all-season comfort. It is perfectly weighted to be used in any weather conditions. It has temperature-regulating properties that help to keep you cool on hot summer nights but provides excellent warmth on cold winter nights without weighing you down. Down can absorb moisture, like sweat, and pass it back to the atmosphere, keeping you and the rest of your bedding completely dry while you sleep. 

Extra Large California King Size Benefits

The Extra Large California Super King Size is meant to accommodate thicker mattress contours and is much larger than the typical California King Size Duvet. It is designed larger to provide fabric draping. This duvet can also be used with smaller mattress sizes when extra fabric draping is wanted or when sharing a duvet. This duvet is perfect for sharing since it has plenty of extra fabric to accommodate two people. 

Care Instruction:

Do not wash this down duvet, as this can cause the filling to leak out. Spot cleaning is recommended. Use warm water and a small amount of mild soap or detergent. Allow the spot to air dry. Always use a duvet cover to protect your comforter. To freshen up your comforter, it is recommended to hang it outside in the sun and air it out for a few hours. This helps to disinfect the down. Fluff and shake out your duvet daily after use to redistribute the filling.

Summer duvet

Just purchased another duvet from DUB for the warmer months here in the South. I already have the 850 Glucksberg, which is like a heavenly cloud, but needed something lighter for warmer months. Terrific pricing, quick delivery, quality product. I trust DUB and you cannot beat their prices for quality bedding products.

We both love the duvet. My tall husband no longer has cold feet, but I love having the extra length at the sides of the quilt so I stay "wrapped" all night. we are both sleeping better. Perfect weight and warmth.
