Using your Thermarest Inflatable Air Head Lite Pillow is easy. First, find a flat spot in your sleeping bag. Open the inflation valve and blow air into the pillow until you reach your desired firmness. You can adjust it by adding or releasing a little air. When you're done using it, open the valve fully and roll the pillow up tightly to squeeze out the air. Then, it can be easily packed into your pocket. For maintenance, keep it away from sharp objects to avoid punctures. If it gets dirty, you can gently wipe it with a damp cloth. Also, store it in a cool, dry place when not in use.
