Salomon’s Sense Jacket is the perfect outer layer for cool weather training as it protects against chilly winds whilst remaining breathable. The windproof fabric has a PFC free DWR (durable water repellency) treatment to help it shrug off drizzle and light rain, with the laser-cut holes on the rear and under the arms aiding airflow. Designed with a svelte Active Fit silhouette, it won’t flap in the breeze or hinder movement and when not needed it can be packed down into its own pocket for easier carrying. If out on the roads after dark, the reflective brand adds extra visibility to traffic.
