How do down blankets hold up agaist moisture?

Down blankets generally do not perform well in humid or moist environments. Down is a natural material derived from the feathers of waterfowl, and like other natural fibers, it is susceptible to moisture absorption. Here's how down blankets hold up against moisture:

1. Moisture Absorption: Down has inherent water-resistant properties due to its natural oils. However, with prolonged exposure to moisture or humidity, down blankets can absorb moisture from the air, leading to a damp or heavy feeling.

2. Loss of Loft: When down absorbs moisture, it can cause the clusters to stick together, resulting in reduced loft and insulation capability. This can lead to the blanket becoming less effective in trapping heat and providing warmth.

3. Mold and Mildew Growth: Moisture trapped within the down filling can create a favorable environment for mold and mildew growth. This can lead to an unpleasant odor and potentially cause health issues for those with allergies or respiratory conditions.

4. Drying Time: Down blankets take longer to dry compared to synthetic blankets. If they get wet, they require proper care and drying to prevent the growth of mold and ensure their longevity.

5. Maintenance and Care: Down blankets require regular maintenance to stay fresh and dry. They should be aired out frequently to prevent moisture build-up and periodically cleaned following the care instructions provided by the manufacturer.

To mitigate these issues, it is recommended to store down blankets in a dry place when not in use. Additionally, using a duvet cover or blanket protector can help protect the down blanket from moisture and stains, extending its lifespan.

For individuals living in humid or damp climates, synthetic or moisture-resistant blankets may be a more practical choice as they are less prone to moisture absorption and better suited to these environments.
