How to use: Just unzip the sleeping bag and get in. You can zip it up fully for more warmth or leave it open a bit for ventilation. If you're a couple, you can zip your Women's Spark to a Unisex Spark for more comfort. When you're done, roll it up and store it in a dry place. It's easy to carry on your adventures. Note: Avoid sharp objects that could tear the bag. Don't expose it to direct sunlight for too long. Maintenance: If it gets dirty, you can spot - clean it with a mild detergent. For a full wash, follow the care instructions on the label. Make sure it's completely dry before storing to prevent mold and mildew.
