PF25 is a performance-driven powder designed for new or very fine-grained snow under dry conditions. It uses Swix CrystalShield technology to create a smooth, hard surface that minimizes friction and delivers long-lasting speed. Best used in snow humidity levels between 0% and 25%. Sprinkle evenly and melt into the ski base using a waxing iron at a minimum of 160°C. Iron slowly (8–10 seconds per ski) for optimal results.
