I’m still searching for a sleeve for my 13” retina and thought I’d post a few of the ones I’ve come across to help others out. The ones listed below are all specifically tailored for the 13” retina. Other brands like Booq, Incipio and Incase are marketing their Air and Pro sleeves for the retina, which wont be a perfect fit. So far these are best I’ve found. Please feel free to add to this.
