Sierra Designs introduces its new Dri Down Technology(thunderous applause). Through outside innovations harnessed by Sierra Designs, Dri Down will change the face of down insulation and expand upon its capabilities. No more will your down insulation become deformed and lusterless as it absorbs moisture over time. Treated with what modern day alchemists refer to as a “hydrophobic polymer”, Dri Down is able to venture beyond the preconceived limits of common down insulation by retaining 98% of its loft and drying 33% faster than other untreated down insulation. Extended life, more function, what’s not to get excited about? Sierra Designs’ Dri Down Technology is a tremendous step in the evolution of Down.
