The FAST POLAR overshoes are a result of the collaboration between Northwave Lab and POLARTEC. The goal was to keep the feet, as the most exposed parts of the body, reliably warm. The inner padding is made from recycled POLARTEC ALPHA DIRECT to ensure warmth and breathability. At the same time, excessive heat and moisture are effectively expelled. This is made possible by the exclusive structures of Alpha Technology, combined with a solid mesh core. POLARTEC ALPHA DIRECT is hydrophobic, moisture-resistant, and dries incredibly quickly. An outer windproof membrane provides additional protection, while reflective details enhance visibility during training.
