Machine wash cold on a gentle cycle with a down-safe technical wash like Nikwax Down Wash or Granger's Down Wash — avoid regular detergent, which strips the natural oils from the 700-fill recycled down clusters and reduces loft.

Close the YKK® zipper fully before washing. Wash the bag separately in a front-loading machine (top-loaders with agitators can damage baffles and snag the shell).

Tumble dry on low heat with two or three clean tennis balls or dryer balls — the balls break up clumps in the down insulation and restore loft after washing. Drying thoroughly (often 2-3 cycles) is essential to keep the down performing at its best and prevent mildew.

Do not bleach, do not use fabric softener, and do not use dryer sheets — all three can coat the recycled down fibers and degrade the loft, the non-PFC DWR finish on the 20D recycled nylon shell.

Do not iron, do not dry clean, and do not wring the bag when wet — wringing can permanently mat the down and damage the trapezoidal baffle walls.

Re-apply a non-PFC DWR spray-on treatment (like Nikwax TX Direct or Granger's Performance Repel) after several washes to refresh the water-shedding performance of the 20D recycled nylon shell.

Store the bag uncompressed (loose in a large cotton or mesh storage sack) in a cool, dry, well-ventilated area when not in use — long-term compression in the stuffsack can reduce down loft and overall warmth over time.

Periodically air the bag outside on a dry, sunny day to keep the recycled down fresh and prevent moisture buildup in storage.

Inspect the YKK® zipper and baffle seams before each trip — small issues caught at home are far easier to repair than in the field.
