My MacBook has never been more eco-friendly inside a notebook sleeve made of 100% recycled materials. The sleeve hugs the 13-inch MacBook perfectly and keeps out unwanted damage, however, it is not the ideal choice for protection.
Both the internal and external fabrics are made of recycled plastic known as PET. The lightweight sleeve fits nicely into my Timbuk2 Hemp/PET bag and stays secure while traveling.
Act2 also produces other green notebook accessories as well as other bags. You can purchase them on their online store and read about the company to find out more information over at their official site. Don?t judge them from their site alone, you need to see the product, it?s really nice looking.
