Down Jackets

Down loses insulation when wet. For damp conditions, pair with a waterproof shell or opt for water-resistant treated down (e.g., DWR-coated). 

Fill power measures loft (e.g., 600FP = higher warmth-to-weight). Fill weight is the total down quantity. High fill power (800+) offers lightweight warmth.

Look for Responsible Down Standard (RDS) certification, ensuring ethical sourcing. Some brands use recycled down or plant-based treatments. 

Wash only when necessary (e.g., stains, odors) to avoid wear. Spot-clean minor dirt, and reproof annually. Overwashing reduces loft and thermal performance. 

No, standard detergents strip the DWR coating and damage down clusters. Use non-biological or technical cleaners (e.g., Nikwax Down Wash) to preserve insulation and water repellency.
