material information TEMPEST ![]() | Bioracer Tempest. Warm. Light. Water repellent. Tempest is a thermal material for winter jerseys en leggings and has a breathable, brushed layer of microfiber and an out layer that protects the body from cold. This textile has undergone a treatment during the weaving process. During this process, special threads are woven into the textile, which form a physical barrier from water. This is how we obtain a material that is water-repellent, breathable, quick-drying and comfortable. Because it is woven in, rather than a coating applied on top, these features are permanent, even after repeated use and washing. |
