Using this sleeping bag is a breeze. First, unpack it from your backpack and lay it out in your tent or camping area. If it's a normal cold night, keep the footbox zipped for maximum warmth. But if you feel a bit cramped, unzip the footbox to stretch your feet. On those extra - cold nights, unzip the extended zipper flaps to cover yourself like a blanket. When it comes to maintenance, make sure the bag is completely dry before packing it away. Avoid storing it compressed for long periods as it can damage the down filling. If it gets dirty, follow the care instructions on the label. Usually, a gentle machine wash with a down - specific detergent is recommended. Also, always air - dry it thoroughly to keep the down fluffy and effective at retaining heat.
