When regular down is exposed to moisture, the moisture droplets cling to the filaments of the down cluster, forcing the down to collapse in on itself. When wet, regular down loses its ability to insulate because the pockets of air that provide insulation collapse. Air pockets on the down clusters of DownTek™ Water Repellent Down do not collapse. A nano treatment creates surface tension on the surface area of the treated down clusters. This surface tension forces the moisture molecules to bead up and roll off the down, leaving each cluster free to continue trapping warm air, thereby maintaining the ability to insulate even when wet.
