Year-round comfort and ventilation

The ALPINESTARS ST-1 WATERPROOF jacket is designed for riding in various climate conditions. In cold weather, you can use the removable thermal liner. A fixed inner layer protects against water. For riding in the heat, there are front ventilation panels, whose system bypasses the waterproof membrane. This allows air to flow directly to the body, helping to regulate temperature. This combination of layers means you can use the jacket all year round.
