Women's On Running Jackets

Women's On Running jackets are constructed for weather protection without compromising breathability — lightweight shells with DWR coatings, ventilated panels, and packable designs. Jackets function as an outer protection layer for variable conditions rather than insulation or thermal retention. OD's stocks the full women's range across weather shells, insulated layers, and packable options.

Fits are athletic and close to the body — true to size for running use. For layering over midlayers in cold conditions, size up one.

Weather Shells

Weather shells are defined by protection from wind and rain without overheating. These styles use lightweight polyamide fabrics with DWR (durable water repellent) coatings that cause moisture to bead and roll off rather than soak through. Breathability is engineered through ventilated zones — typically underarm panels or back vents — that allow heat and moisture to escape during sustained effort. They are not designed for static weather protection; prolonged exposure to heavy rain will overwhelm lightweight DWR-treated fabrics.

Construction is minimal to reduce weight and bulk. Most weather shells pack into their own pocket for storage when conditions change. Hoods are adjustable and cut to maintain peripheral vision. Reflective details add visibility in low light.

Insulated & Midlayers

Insulated jackets provide warmth for cold-weather training and warm-up use. These styles combine lightweight insulation with breathable outer fabrics to retain heat without causing overheating during movement. They function as standalone layers in mild cold or as midlayers under shells in harsher conditions. These garments are intended for warmth and layering rather than sustained high-output running.

Construction is typically quilted or panelled to allow articulation. Fits are slightly roomier than weather shells to accommodate base layers beneath.

Packable & Travel

Packable jackets prioritise portability for variable conditions. These styles compress into compact sizes for carrying and deploy quickly when weather changes. Protection is lighter than dedicated weather shells — suited to showers and wind rather than sustained rain.

Packability is achieved by reducing fabric weight and structure, trading long-term durability for portability.

Materials Across the Range

On jackets primarily use polyamide (nylon) for weather resistance and durability, often combined with elastane in high-movement zones. DWR coatings provide water repellency but are not waterproof — heavy sustained rain will eventually soak through. Insulated styles use synthetic fills that retain warmth when damp. Exact compositions vary by style. Refer to individual product pages for confirmed specifications.

Care

Machine wash cold on a gentle cycle. Avoid fabric softener, which degrades DWR coatings. Tumble dry low — heat reactivates DWR treatment. DWR coatings degrade over time and require periodic reapplication to maintain water repellency.
