Introduction

This manual provides essential information for the proper use, care, and maintenance of your sleeping bag.

Key Features

  • Temperature Rating: 20 Degree Fahrenheit.
  • Insulation: Cirroloft synthetic insulation for reliable warmth in cold and damp conditions.
  • Fabric: 380T nylon taffeta shell and 50D 300T polyester taffeta lining.
  • Packability: Integrated compression stuff sack for compact storage.
  • Design: Mummy shape with a natural fit spacious footbox for comfort.

Setup

  1. Unpack: Remove the sleeping bag from its compression stuff sack.
  2. Allow Loft: Lay the sleeping bag flat and allow several minutes for the synthetic insulation to fully loft and expand. This maximizes its insulating properties.
  3. Position: Place the sleeping bag on a suitable sleeping pad inside your tent or shelter.

Operating Instructions

  1. Entering the Bag: Unzip the sleeping bag fully. Slide in, ensuring your feet are comfortably in the footbox.
  2. Zipper Operation: The bag features dual locking sliders. Use these to adjust ventilation from the top or bottom. The anti-snag treatment helps prevent fabric from catching in the zipper.

Maintenance

Cleaning

  • Spot clean small areas with a damp cloth and mild soap.
  • For a full wash, use a large capacity front-loading washing machine. Use a technical wash designed for synthetic insulation or a mild, non-detergent soap.
  • Wash on a gentle cycle with cold water.
  • Rinse thoroughly to remove all soap residue.
  • Tumble dry on low heat with a few tennis balls to help break up clumps of insulation and restore loft. Ensure the bag is completely dry before storing.

Storage

  • Store the sleeping bag uncompressed in a large mesh storage sack or hung in a closet. Prolonged compression can reduce the loft and insulating effectiveness of synthetic fill.
  • Keep the bag in a cool, dry place away from direct sunlight.

Troubleshooting

  • Cold Spots: The bag features offset quilt construction to minimize cold spots. If you experience cold spots, ensure the bag is fully lofted and not compressed in any areas. Adjust your sleeping position or add a liner for extra warmth.

  • Zipper Snagging: While designed with anti-snag treatment, rapid or forceful zipping can still cause fabric to catch. Operate the zipper smoothly and guide the fabric away from the zipper teeth.
  • Reduced Warmth: Ensure the bag is clean and fully lofted. A dirty or compressed bag will lose insulating power. Consider your sleeping pad's R-value, as significant heat loss occurs through the ground.
