FAQs

Is this jacket suitable for heavy rain?

No, the jacket has a water-repellent finish which is effective against light showers only. For heavy rain, it is recommended to wear a waterproof outer shell over the jacket.

How do I clean the jacket?

Machine wash on a gentle cycle with a mild detergent. Tumble dry on a low heat setting with tennis balls to help restore the down's loft. Ensure it is completely dry.

What does RDS certified mean?

RDS stands for Responsible Down Standard. It means the down and feathers used in the jacket come from farms that have been certified to meet high animal welfare and traceability requirements.

What is Fill Power 700?

Fill Power is a measure of the down's loft or fluffiness. A rating of 700 indicates a high-quality down that traps more air per ounce, providing excellent insulation for its weight.

Can I store the jacket compressed?

While the jacket is designed to be packable, it is best not to store it compressed for extended periods. Store it loosely to maintain the down's loft and long-term insulating performance.

What is the benefit of the packable design?

The packable design means the jacket can be easily folded or stuffed into its own pocket or a separate stuff sack, taking up minimal space in a backpack or luggage, making it ideal for travel and outdoor activities.

Is this jacket warm enough for very cold winter conditions?

The jacket provides excellent lightweight warmth suitable for moderate cold or as a layering piece. For extreme cold, it is recommended to layer it with other insulating garments.

Troubleshooting

Jacket seems to have lost some loft/warmth

The down may have clumped. Try washing and drying the jacket according to the care instructions, using tennis balls in the dryer to help redistribute and restore the loft.

Water repellency is reduced

The DWR (Durable Water Repellent) finish may have worn off. Consider reapplying a DWR treatment suitable for down jackets after washing and drying.

Jacket is not drying properly

Ensure the tumble dryer is set to a low heat. Drying down can take a long time; continue drying in cycles until completely dry to prevent mildew and clumping.

Zipper is sticking

Gently try to move the zipper up and down. If it continues to stick, check for any fabric caught in the teeth. You can use a graphite pencil tip or a small amount of wax to lubricate the zipper teeth.

Pros and Cons

Pros

  • Extremely lightweight for its warmth.
  • Responsibly sourced down (RDS certified).
  • Compresses into a small size for easy travel.
  • Effective insulation for its weight class.
  • Water-repellent finish provides protection from light moisture.

Cons

  • Water repellency is only effective against light showers, not heavy rain.
  • Down fill may not be suitable for individuals with down allergies.
  • Requires specific care to maintain down loft and performance.
  • Not designed as a primary jacket for extreme cold without layering.
  • Zipper pull could be more robust for frequent use.

Setup, Compatibility & Care Instructions

Setup: The jacket requires no setup. Simply unpack and wear.

Compatibility: This jacket is designed for adult women. It pairs well with various base layers and mid-layers for enhanced warmth and is compatible with waterproof outer shells for full weather protection.

Care Instructions:

  • Washing: Machine wash on a gentle cycle with a mild detergent. It is recommended to wash with a few clean tennis balls or dryer balls to help maintain the down's loft.
  • Drying: Tumble dry on a low heat setting with the tennis balls. It may take several cycles to dry completely. Ensure the down is fully dry to prevent clumping and maintain insulation.
  • Storage: Store the jacket loosely rather than compressed in its stuff sack for long periods to preserve the down's loft and longevity.
  • Cleaning Stains: For minor stains, spot clean with a damp cloth and mild soap.
