    • Overlapping draft tubes prevent cold spots when zippers are closed

    • Shell fabric has been treated with a durable water repellent (DWR) to shed moisture
    • Quilt and blanket loops let you securely attach additional insulation (not included)
    • Responsible Down Standard certification ensures that the waterfowl in the down supply chain are treated humanely
