I bought a 15-inch MacBook Pro with Retina display this summer, and I’m absolutely in love with it. I firmly believe that it’s the best laptop Apple has ever made, and it has totally changed my workflow.

One of the main qualities of the Retina MacBook Pro is its portability. It’s crazy thin. I carry this laptop with me everywhere, and I knew when I bought it that I needed something to help keep it protected.

I’ve been using Mujjo’s wool MacBook sleeve nonstop for the past couple months, and I couldn’t be more pleased.
