• Premium 800-fill-power hydrophobic, PFC-free, 100% RDS Certified down is traceable and ensures humane treatment throughout the supply chain
• Full-length double-slider #5 YKK zipper with zipper plow makes getting in and out of the bag a breeze
• Integrated pillow pocket allows a jacket, extra clothes or Fillo™ (not included) to be stuffed into the sleeve opening for secure, elevated support through the night
• Durable water repellent (DWR) on shell fabric and lining fabric prevents the first line of defense against moisture
