FAQs

Is the On Core Running Jacket waterproof?

The jacket is designed for wind and light weather protection, not as a dedicated waterproof garment.

Does it have pockets for keys or cards?

The Core series prioritizes a streamlined, lightweight profile to minimize bulk while running.

Can I wear this for activities other than running?

While optimized for running, its ergonomic fit makes it suitable for cycling or brisk walking.

How should I choose the right size?

It is designed for a close-to-body performance fit; choose your standard athletic size for optimal results.

How do I best store the jacket?

Hang it in a cool, dry place away from direct sunlight to prevent fabric degradation.

Troubleshooting

Jacket feels slightly restrictive when layered

Ensure your base layer is thin and moisture-wicking; avoid thick cotton shirts that create friction.

Fabric feels damp after high-intensity training

The jacket is breathable, but internal condensation is common during extreme exertion. Allow it to air out thoroughly between sessions.

Pros and Cons

Pros

  • Unrestricted range of motion for better running form
  • Easy to layer over technical base garments
  • Lightweight and highly packable for transition periods
  • Professional, ergonomic fit suitable for various body types

Cons

  • Not intended for heavy, prolonged rain exposure
  • Limited warmth in freezing sub-zero temperatures
  • Specific fit may require exact sizing for optimal comfort

Setup, Compatibility & Care

For the best fit, pair this jacket with a moisture-wicking base layer to maximize breathability. To maintain the jacket's performance, machine wash on a cold, gentle cycle using a technical fabric detergent. Avoid fabric softeners, as they can compromise the moisture-wicking properties of the textile. Air drying is highly recommended to preserve the integrity of the fabric and the shape of the garment, though tumble drying on a very low heat setting may be used if the care tag allows.
