![Genuine Fourth Element Men's Xcore Vest + Free Bonus [qzcnF8MQ]](https://cdn.shopify.com/s/files/1/1783/5889/products/fourth-element-x-core-vest_5c2c0e85-fbcc-4fa1-a0b3-34c0527248d5.jpg?v=1546531367)
The physiological response to cold stress is to reduce blood flow to the periphery and look after the body core, where it can often just be a matter of time before cold becomes the limiting factor in the safety and enjoyment of a dive. X-Core provides extreme thermal protection to the core, enabling longer, more comfortable dives.
Designed to be worn under an Arctic, Arctic Expedition, Halo 3D or any other drysuit undergarment, X-Core augments thermal protection to the extent that electric heating can be avoided in many instances. It performs best over a lightweight baselayer such as J2 or Xerotherm but the X-Core can also be worn as a next-to-skin garment for critical core protection.
OceanPositive:
More than 8 million tonnes of plastic are dumped in our oceans every year, endangering marine and bird life and creating almost unfathomable areas of pollution, from local water courses to vast plastic gyres. Reducing the plastic we discard is part of the solution to improving the health of our oceans.
X-Core is made with REPREVE® – a fibre that is made from recycled post-consumer waste, including used plastic bottles. Plastic is removed from the waste stream and prevented from reaching the ocean. 76% of the fibre composition of X-Core is recycled polyester.
The Polartec® fabric used in X-Core is manufactured to the highest environmental standards. It has Blue Sign® and Oeko-Tex® certification to indicate that harmful chemicals are minimised or eliminated and that waste water is treated to ensure its purity before being released from the factory.
