Special Notes

• Use mild detergent

• Tumble dry low to restore loft

• Machine washable unlike most insulations

Additional Care Tips

  • • Machine wash cold (30°C/85°F) on gentle cycle with mild, non-detergent soap
  • • Tumble dry on low heat with clean tennis balls to restore loft — similar to down care
  • • Do not dry clean — solvents can damage the ultra-fine insulation fibers
  • • Store uncompressed in a large breathable bag — prolonged compression reduces insulation performance
  • • Avoid bleach and fabric softener which coat and degrade the fine polyester fibers
  • • Spot clean the outer shell for minor stains to extend time between full washes
