Using your Sea to Summit Tanami I Down Comforter is easy. First, lay it on your mattress and use the drawcord at the base to snug it up so it stays in place. This comforter is great for camping trips, overlanding adventures, or just living in your van. When it comes to cleaning, it's best to follow the care instructions on the label. Usually, you can machine - wash it on a gentle cycle with a mild detergent. After washing, make sure to dry it thoroughly on a low - heat setting, fluffing it up every now and then to maintain the loft of the down. Avoid using harsh chemicals or bleach as they can damage the fabric and the down. Also, store it in a cool, dry place when not in use. If possible, store it in a breathable bag instead of compressing it for long periods, as this can affect the down's loft and performance.
