When the weather turns mid-run, the Women’s Trail Breaker Midlayer from On gives you a performance edge. Designed for trail runners who demand comfort without compromise, this midlayer blends protection, flexibility and smart design in one lightweight package. It’s breathable where you need airflow, water-resistant where you need protection, and crafted to move naturally with your body. Whether it’s cool wind, light rain or sudden changes in elevation, this jacket helps you stay focused and fast.
Built with recycled four-way stretch fabric and a durable water-repellent coating, the Trail Breaker offers adaptive comfort on the trail. The high quarter-zip allows for quick ventilation, while thumb holes keep your sleeves secure as you move. A watch window lets you check your splits mid-stride without pulling back your sleeve. Even the hood packs away into the collar, giving you options without the bulk. Air vents under the arms and at the back ensure airflow is steady when the pace picks up.
Smart details make this jacket a go-to for anyone who moves fast and travels light. It fits true to size with a regular, easy-wear shape that layers comfortably over base gear. The raglan sleeves and tapered cuts enhance freedom of movement, whether you're dodging roots or powering uphill. Best of all, it's compact enough to stash in a running vest or travel pack. Ideal for misty bush tracks, early morning runs or unpredictable mountain weather—this is the layer that moves with you.
