On Running Ultra Jacket – Women's Waterproof Trail Running Jacket

When Australia's trails turn wild, the On Running Ultra Jacket Womens keeps you moving. Engineered for women who demand lightweight protection without compromise, this waterproof trail running jacket pairs On's signature GuardTec™ 2.5-layer technology with a motion-inspired fit built for the demands of technical trail running. Available exclusively at Run Trails.

Why Women's Trail Runners Choose the On Running Ultra Jacket

Stay Dry, Go Further

Designed for Australia's unpredictable weather, the On Running Ultra Jacket Womens features On GuardTec™ 2.5-layer waterproof, breathable polyamide fabric with fully taped seams — delivering a reliable shield against rain while maintaining optimal breathability so you can push harder for longer.

Ultralight Packable Protection

Weighing in at just ~107 g (men's reference weight), this jacket breathes with you rather than weighing you down. When the skies clear, it packs neatly into its hood-integrated mesh pouch — so you're never caught unprepared and never carrying dead weight.

Engineered for Women's Movement

The motion-inspired design minimises friction and adapts to the natural fluidity of a woman's stride. Whether you're climbing switchbacks or descending technical singletrack, the jacket moves with you — not against you.

Trail-Vest Compatible Fit

Running with a hydration vest or small pack? Two integrated rear pleats expand the fit without bunching, making it easy to layer up or shed the jacket mid-run without breaking stride.

Low-Light Visibility

Safety is non-negotiable on the trails. Reflective logos on both the front and back enhance visibility during dawn, dusk, and low-light conditions — so you're seen when it matters most.
