Using this Ascent 1100 down sleeping bag is easy. Just unzip the compression stuff sack and let the bag fluff up for a while to regain its full loft. When you're ready to sleep, simply get inside and zip up the main ¾ length zip. The close - fitting neck baffle can be adjusted around your neck to keep the heat in. You can store small items like your phone or headlamp in the internal zipped stash pocket. If you're with a partner, make sure you have one left - zipped and one right - zipped bag so you can zip them together. When it's time to pack up, first put the bag in the cotton storage sack. Then, use the compression stuff sack to compress the bag for easy transport. For maintenance, keep the bag dry. If it gets wet, dry it thoroughly in a well - ventilated area. Avoid machine - washing as much as possible, as it can damage the down. If necessary, follow the instructions on the care label for gentle cleaning.
