As a natural material, even the whitest down in the world can contain dark spots.
With a conservative estimation of around 1000 down clusters per gram, even down sourced and traditionally separated to 99.9% white, still has the potential to contain at least 1 dark spot per gram.
ALLIED has worked with innovative machinists to develop a computerized sorting process that mechanically separates down cluster by cluster, picking out any dark spots. What is left is a pure white down with virtually no dark spots.
All UltraWHT down is processed in the same way as all ALLIED down in our proprietary DuraWash process and sourced from our certified farms.
