ExpansionKnee

A knee can be bent up to 160 °; however, most undergarments can’t withstand this stress without being pulled thin and results in a loss of functional insulation. The accordion principle behind the ExpansionKnee improves its insulating character rather than losing it when the knee is best. A highly flexible system of chambers and channels provide insulation by storing warm air inside.
