Specially developed for hunters, the First-on-Skin Energizer is equipped with the 3D BionicSphere® System on the chest and back, which uses the cooling function of sweat. Instead of entirely drying off, it leaves some residual moisture on the skin that effectively supports the body’s cooling during deerstalking. Integrated InnerAirChannels store warm air and protect the body from cooling down when sitting on the high seat. AirDuct Pads located on the shoulders and hips aid ventilation and cushioning. The integrated nanotechnology reduces bacterial growth so that unpleasant odours don’t develop.
