FAQs

Is the jacket fully waterproof?

It is water-repellent due to the anti-drop agent, meaning it protects against light rain and snow, but it is not a fully waterproof rain jacket.

Can I machine wash this jacket?

It is recommended to follow the specific garment care label. Generally, professional care is preferred to maintain the integrity of the garment-dyed finish and anti-drop coating.

What does RDS-certified mean?

RDS stands for Responsible Down Standard, ensuring that the feathers are sourced from ducks and geese that are treated humanely and not subjected to unnecessary harm.

How should I store the jacket during summer?

Store it hanging in a breathable garment bag, away from direct sunlight and humidity, to keep the down lofted and prevent fading of the dye.

Is the fit true to size?

The jacket generally follows standard sizing, though it is designed as a technical piece; consider if you intend to layer heavy knitwear underneath when selecting your size.

Troubleshooting

Visible down poking through seams

This is rare due to the seamless construction, but if minor fibers appear, gently pull them back inside rather than plucking them, which can widen the opening.

Water repellency seems to decrease

The anti-drop coating can be revived by following the manufacturer's care instructions, or by using a specialist garment-safe re-waterproofing spray.

Zipper feels stiff

Ensure no fabric is caught in the track and wipe the zip teeth with a clean, dry cloth to remove dust or debris.

Pros and Cons

Pros

  • Innovative seamless design prevents down leakage
  • Lightweight, stretch-nylon material allows for excellent mobility
  • Integrated anti-drop agent provides reliable water repellency
  • Clean, minimalist aesthetic with signature brand identity

  • Garment-dyed finish requires strict care guidelines
  • Single-layer stretch fabric may be prone to snagging on sharp objects

Setup, Compatibility & Care

Because this jacket utilizes a specialized garment-dyeing process and an anti-drop coating, care is essential to extend its lifespan. Always check the internal wash label before cleaning. Typically, professional dry cleaning or professional wet cleaning is recommended to avoid damaging the specialized fabric treatment. When not in use, store the jacket in a cool, dry, and well-ventilated area, preferably on a wide-shouldered hanger to maintain the shape of the padded hood and shoulders. Avoid prolonged storage in compressed bags, as this can degrade the loft of the RDS-certified down over time.
