Hypoallergenic - Down that has gone through a series of steps to remove all the impurities, dirt and dander, will be noted as hypoallergenic or allergy free. Most people are not allergenic to down, but rather, to the impurities within the down. Not all Down Comforters are hypoallergenic

Baffle Box Construction - Baffle box means there are thin strips of material sewn between the top and bottom covers that form a grid of square boxes (called baffles). The baffles prevent the down from shifting to the sides of the comforter and allows the down to loft more evenly throughout the comforter eliminating cold spots.
