With it's trademarked EnviroDown®, Down Lite takes an extra step in the cleaning process that sets it far above the competition. After going through the normally extensive washing, the down is placed into a containment chamber that sanitizes the fill at a temperature of 195 degrees Fahrenheit. To complete the process, the fill is placed into an ozonation chamber that eliminates odors and bacteria for a super-clean, hypo-allergenic product that is less likely to cause an allergic reaction than regular down and feathers. Down Lite also holds the patent for the Perma-Baffle comforter construction. This comforter design is the best performing baffle box comforter available. Its inter-locking baffles completely eliminate down shifting, even during washing, while maintaining the loft and lack of 'cold spots' associated with sewn-thru box comforters. Also, most of Down Lite's comforters are over-sized to accommodate the thicker mattresses available today.
