The Tech Sling 3 X-Pac is a versatile sling bag designed for tech essentials. It's made with lightweight and waterproof Dimension-Polyant® VX-42 X-Pac fabric. Features include a padded PC pocket, multiple pockets for gear storage, and a reversible shoulder strap that can be used on either side. A Mac Air fits in it with room to spare. I purchased it in October of this year, but I'm hesitant to use it because my company's large laptop is a tight fit, making it difficult to take on business trips. (My Mac fits, and I like the look and usability.) It looks almost new. Price on the Aer official website: 30,800 yen Thank you for your consideration.
