WaveLoft Construction

WaveLoft is a unique construction technology designed to maximize loft and minimalize insulation weight. Instead of conventional flat layers of insulation (sewn flat on top of each other) or shingle layers (sewn in diagonally overlapping layers), WaveLoft creates curved layers which expand out from the shell to trap the greatest amount of air possible at a lower overall weight than existing synthetic insulation constructions.

WaveLoft is used on all Sea to Summit synthetic-insulated sleeping bags, regardless of price level.
