Using this Incase Reform brief is a breeze. First, open the three - sided zip butterfly design to easily place your 15' Macbook, iPad, and accessories inside. Use the dedicated iPad sleeve and accessory organizer pockets to keep things tidy. When traveling, simply open the brief flat for airport security screening. For the handle and shoulder strap, they are designed for comfort during carrying. As for maintenance, use a soft, damp cloth to gently clean the exterior. Avoid exposing it to extreme heat or sharp objects that could damage the material. If the shoulder strap gets dirty, you can detach it and clean it separately. And that's all you need to know to make the most of your Incase Reform brief.
