Ventrix™ 100% Polyester Stretch Insulation | 80g: Designed for highly aerobic activities in variable weather conditions, Ventrix™ adapts to the wearer's body movement and actively regulates body temperature by radically balancing warmth and breathability. Perforations in key zones open with movement, allowing excess heat and perspiration to escape when aerobic output is high so the wearer doesn't overheat and sweat out. During times of decreased activity, the perforations remain closed, sealing in heat to keep the wearer warm and ready for the next effort.
