This often indicates the DWR (Durable Water Repellent) coating needs refreshing. First, clean the jacket as per care instructions. If the issue persists, apply a suitable DWR spray or wash-in treatment to the outer fabric.

Ensure the jacket is clean and dry. Dirt and oils can flatten insulation. If cleaning doesn't help, ensure proper layering underneath; thin layers work best. Also, check that the insulation isn't permanently compressed; gentle tumble drying with tennis balls can sometimes help restore loft.

Clean the zipper teeth with a small brush and mild soap to remove any dirt or grit. Once dry, apply a specialized zipper lubricant or a small amount of graphite from a pencil to the teeth to improve glide. Avoid forcing the zipper.
