The Fourth Element X-Core line is top-of-the-line products that have as much insulating effect as other electrically heated undergarments. Here you get a product that holds and amplifies your own body heat.
The Fourth Element X-Core vest's sleeveless design minimizes the effect of buoyancy and your overall weight, especially around shoulders and sleeves where freedom of movement is crucial. Designed in four-way stretch material in combination with the long body design, great fit and minimizing areas where you usually get cold. The extra chest panel creates greater distances and minimizes the feeling of cold air and also provides greater thermal insulation around the internal organs.
The vest's material transports moisture to the outside of the vest, which keeps you dry.
