Using this sleeping bag is easy. First, take it out of the Ultra - Sil compression bag. Unzip it and spread it out in your tent or sleeping area. You can adjust the temperature by using the Free - Flow zipper system. For warmer nights, open the zippers to let in air. For colder nights, close them up and use the shaped hood and draft collar to keep warm. Keep your small items like phone or GPS in the internal pocket. When you're done using it, clean it gently according to the care instructions on the label. Store it in the provided storage cell in a dry place. If you want to travel with it, use the compression bag to make it more compact. Also, make sure not to over - compress the bag for long periods as it may damage the down. And when zipping it to another compatible sleeping bag, be careful with the zippers to avoid jams.
