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, 10–20g lighter than shells with separate stuff sacks.
Packability
Packs to a 5-inch sphere and stows in one motion into its front pocket.
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.
Hem drawcord
Adjustable hem drawcord cinches the jacket securely to the hips.
Breathability
Knit fabric blocks wind yet breathes; storm flaps and drawcords release heat incrementally.
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.
Reflective details
Reflective trim on chest, rear vent, and sleeves provides 360-degree visibility.
Athletic design
Packs into its own pocket, moves freely, and layers over a base layer.
Materials and reputation
Manufactured from 87-95% recycled polyamide; endorsed by Reddit users.
Self-stowing
Self-stows into its front pocket; DWR maintains packability in light rain.
Pack size
Weighs 159g and packs to grapefruit size; compresses without creasing.
Temperature regulation
Adjustable storm flaps and drawstrings let you seal or release warmth mid-run.
Layering fit
Raglan sleeves and 13% elastane stretch comfortably over thick mid-layers.
