Product Insights
The On Core Running Jacket is a 159g windproof knit shell that packs into its own pocket to grapefruit size mid-run, trading heavy downpour protection for breathable wind-blocking, adjustable ventilation, and a stretchy athletic fit that moves freely over layers. Its recycled polyamide fabric resists wet-out from light rain and avoids membrane delamination, while reflective trim and a secure hem drawcord make it a purposeful cold-weather layer that sheds heat when needed.
Verified claims
- Mid-run stow
- Packs into its own pocket in one motion, even mid-run.
- Packed size
- Compresses to grapefruit size (5x5 in sphere) without permanent creasing.
- Weight
- Weighs 159g (men's medium); because its front pocket doubles as the stuff sack, its packed weight is 10–20g less than shells that require a separate stuff sack.
- Windproof knit
- Tightly-knit fabric blocks wind yet remains breathable and stretchy.
- Ventilation control
- Adjustable storm flaps and drawcord let you control airflow.
- DWR
- DWR sheds light rain and prevents wet-out, but not heavy downpours.
- Wind protection
- Windproof knit with adjustable hem/hood seals out drafts; storm flaps allow ventilation without wind entry.
- Water resistance
- DWR treatment beads water to prevent fabric wetting and heat loss; can be heat-reactivated.
- Visibility
- Reflective elements improve visibility in low-light winter runs.
- Range of motion
- Spiral dart construction prevents across-the-back pull during arm swing.
- Temperature range
- Best for cold winter runs; packs into its pocket to shed mid-run when heat builds.
- Hem adjustability
- Adjustable hem drawcord cinches the jacket tightly to hips to prevent riding up.
- Recycled content
- 87-95% recycled polyamide, waste-derived, throughout the jacket.
- Fabric durability
- The knit fabric construction avoids membrane delamination.
- Materials and reputation
- The main fabric is 87% recycled polyamide, secondary panels are 92% recycled polyamide, and the lining is 95% recycled polyamide.
- Layering fit
- Raglan sleeves and 13% elastane stretch comfortably over thick mid-layers.
- Fit comparison
- The Core Running Jacket offers a regular, athletic fit that accommodates light layering and is not as slim as On's elite racing shells.
- DWR maintenance
- The factory DWR can often be revitalized by machine washing the jacket and then tumble drying on low heat for 20 minutes; the heat realigns the polymer chains and restores water beading.
- Front pocket storage
- The zippered front pocket doubles as the stuff sack and is robust enough to hold a phone and keys, so there is no detached pouch to lose.

Running through wind and rain
This running jacket is made for cold, blustery runs, with light windproof knit material that stays breathable so you aren't trapping in sweat. Its water-repellent DWR treatment keeps raindrops rolling off, while the adjustable drawstrings on the attached hood and hem help seal out rain and cold. Raglan sleeves and a spiral dart construction allow movability for your stride.[1,3,4,5]
Packs into its own pocket for easy carrying
When the weather warms up and you no longer need the jacket on, it packs into its own front pocket so you can stash it and get on your way without lugging it around. Handy for tossing into a bag or carrying by hand during a run or outing.[1,2,3]
Running in low light, from early mornings to evening laps
For runs when it's dark out, this On running jacket is designed with reflective details intended to help keep you visible. A short angled reflective strip sits on the right edge of the chest overlay flap, and curved reflective trim runs across the upper torso.[4,5,6]
