Using your Osprey Ultralight Stuff Pack is a breeze. Just unroll it and start packing your items. You can use the side pockets for small, frequently - used things like water bottles or snacks. The key clip inside the pack is great for keeping your keys easily accessible. When you're done using it, simply stuff it back into a small space. As for maintenance, it's best to clean it with a mild detergent and cold water. Avoid using harsh chemicals as they can damage the fabric. Also, don't machine - dry it; instead, let it air dry. When not in use, store it in a cool, dry place to keep it in good condition.
