Using your Incase sleeve for the 13' MacBook Air is super easy. Just slide your laptop gently into the sleeve. You can carry it on its own or place it inside your larger bag for extra protection. When it comes to cleaning, use a soft, dry cloth to wipe off any dust or dirt. Avoid using harsh chemicals as they may damage the eco - dyed poly material or the faux fur lining. Also, don't overstuff the sleeve with other items as it's specifically designed to fit the 13' MacBook Air. By following these simple steps, you can ensure your sleeve lasts a long time and keeps your laptop safe.
